ChangeLog-2013

2013-12-28  Arthur de Jong <arthur@arthurdejong.org>

	* [e3f0453] configure.ac: Re-organise ldap function tests

2013-12-21  Arthur de Jong <arthur@arthurdejong.org>

	* [3ce5ef9] : Make dn2uid cache tuneable

	  This introduces a new cache configuration option that allows
	  setting positive and negative cache lifetimes for the dn2uid cache.

	* [19f3cc3] tests/test_cfg.c: Add a test for new configuration option

	* [09969cf] man/nslcd.conf.5.xml: Document cache option in
	  manual page

	* [a0c90d2] nslcd/passwd.c: Use dn2uid cache options

	  The configuration values are used in the cache to determine
	  positive and negative hit TTLs. This also allows completely
	  disabling the cache.

	* [99ad1b4] nslcd/cfg.c, nslcd/cfg.h: Implement a cache configuration
	  option

	  This adds the cache nslcd.conf configuration option to configure
	  the dn2uid cache in nslcd with a positive and negative cache
	  lifetime.

2013-12-19  Arthur de Jong <arthur@arthurdejong.org>

	* [82bac61] nslcd/passwd.c: Have positive and negative cache timeouts

	  The positive value determines the time a found entry is valid,
	  the negative timeout determines the lifetime of not found entries.

	* [b9ec6df] nslcd/cfg.c: Support printing children search scope

	  This fixes 2caeef4.

2013-12-18  Arthur de Jong <arthur@arthurdejong.org>

	* [9f02853] nslcd/alias.c, nslcd/common.c, nslcd/common.h,
	  nslcd/ether.c, nslcd/group.c, nslcd/host.c, nslcd/myldap.c,
	  nslcd/netgroup.c, nslcd/network.c, nslcd/pam.c, nslcd/passwd.c,
	  nslcd/protocol.c, nslcd/rpc.c, nslcd/service.c, nslcd/shadow.c,
	  nslcd/usermod.c: Centralise buffer sizes

	  Common buffer sizes are now stored centrally so it can be easily
	  and consistently updated if required. Some buffers remain with
	  locally defined sizes that do not match a global buffer size.

2013-11-25  Arthur de Jong <arthur@arthurdejong.org>

	* [23a41ce] compat/pam_get_authtok.c, compat/pam_prompt.c,
	  configure.ac, pam/pam.c: Add a test for pam_get_item() argument
	  type

	  This checks whether pam_get_item() takes a const void ** or void
	  ** item value argument and defines a PAM_ITEM_CONST macro that
	  is const when it should. This avoids some compiler warnings.

2013-10-30  Arthur de Jong <arthur@arthurdejong.org>

	* [81bfb8b] ChangeLog, NEWS, configure.ac, man/chsh.ldap.1.xml,
	  man/getent.ldap.1.xml, man/nslcd.8.xml, man/nslcd.conf.5.xml,
	  man/pam_ldap.8.xml, man/pynslcd.8.xml: Get files ready for
	  0.9.2 release

2013-10-29  Arthur de Jong <arthur@arthurdejong.org>

	* [ef0edda] tests/test_myldap.sh, tests/test_nsscmds.sh,
	  tests/test_pamcmds.expect: Portability fixes to environment tests

	  This mostly tries to reduce the influences of the test environment
	  (local users and groups) on the tests. This uses another username
	  (vsefcovic) in the PAM tests instead of the user arthur to avoid
	  clashes with existing users.

	  The PAM tests are skipped if passwd claims that it cannot modify
	  LDAP passwords (for FreeBSD).

	* [f8af48f] compat/ldap_parse_passwordpolicy_control.c,
	  nslcd/common.c, nslcd/config.c, nslcd/group.c, nslcd/nslcd.c,
	  nslcd/pam.c, nslcd/protocol.c, nslcd/rpc.c, nslcd/service.c,
	  nss/bsdnss.c, nss/ethers.c, nss/group.c, nss/netgroup.c,
	  nss/networks.c, nss/passwd.c, nss/protocols.c, nss/rpc.c,
	  nss/services.c, pam/pam.c: Fix a number of compiler warnings

	  This includes a number of small fixes for issues that were
	  formerly masked by the incorrect AC_LANG_PROGRAM check.

	* [88801f9] configure.ac: Add -Werror=implicit if compiler
	  supports it

	* [933bf8e] configure.ac: Fix usage of AC_LANG_PROGRAM

	  Apparently the macro got changed a long time ago to provide a
	  main() definition. This bug caused the extra warning flags to
	  not be added.

	* [6028226] compat/Makefile.am, compat/shell.h, configure.ac,
	  nslcd/usermod.c: Compatibility definitions for
	  {set,get,end}usershell()

	  This provides compatibility definitions for systems that don't
	  have these functions (some Solaris flavours).

2013-10-28  Arthur de Jong <arthur@arthurdejong.org>

	* [ed4cf47] nslcd/nslcd.c: Start invalidator after locking pidfile

	  This causes the pidfile to be written as the first thing after
	  daemonising nslcd to minimise the race between service script
	  completion and pidfile being locked.

2013-10-27  Arthur de Jong <arthur@arthurdejong.org>

	* [503644b] HACKING, README: Update documentation

	* [6be316e] autogen.sh, configure.ac: Specify m4 directory in
	  configure script

2013-10-25  Arthur de Jong <arthur@arthurdejong.org>

	* [1d8db24] nslcd/myldap.c, pynslcd/search.py: Also run invalidators
	  on initial connect

	  This also invalidates the caches configured with
	  reconnect_invalidate on the first successful search. This should
	  handle the case more gracefully where caches were filled with
	  negative hits before nslcd was running.

	* [ee8737f] tests/Makefile.am: Distribute setup_slapd.sh and
	  associated files

2013-10-22  Arthur de Jong <arthur@arthurdejong.org>

	* [e28e937] tests/test_myldap.sh, tests/testenv.sh: Improve
	  portability of ldap test

	  This supports old ldapsearch commands that don't support the -x
	  and -H options and ldapsearch commands that don't exit with a
	  failure code if nothing is found.

	  This also switches the test_myldap test to use the testenv check
	  for the LDAP server.

2013-10-20  Arthur de Jong <arthur@arthurdejong.org>

	* [8cc354a] tests/test_pamcmds.expect: Handle other responses
	  in test_pamcmds

	  This extends test_pamcmds to handle other pam/su/passwd errors
	  and responses (as seen on CentOS 5). Also switch to stronger
	  password when changing the test user's password to avoid problems
	  with password strength checks.

	* [0a95557] tests/Makefile.am, tests/in_testenv.sh,
	  tests/test_nsscmds.sh, tests/test_pamcmds.expect,
	  tests/test_pamcmds.sh, tests/testenv.sh: Make script to check
	  test environment

	  This changes the in_testenv.sh script into testenv.sh which has
	  more checks and a few functions to configure the test environment.

	* [1899e9a] tests/test.ldif: Remove unnecessary attributes from
	  test.ldif

	* [cebc2a1] tests/README: Update tests README

	  This refreshes the documentation of the tests, especially the
	  test environment.

	* [7cbb439] tests/config.ldif, tests/setup_slapd.sh: Provide a
	  script for setting up slapd

	  The setup_slapd.sh script can be used to set up and start a
	  slapd instance in a single (temporary) directory. The slapd
	  instance is configured and loaded with test data for use in the
	  test environment.

2013-10-19  Arthur de Jong <arthur@arthurdejong.org>

	* [aeccbfe] tests/test_nsscmds.sh: Fix sortgroup function

	  This fixes an issue with the sortgroup function which failed to
	  handle a group line with only two colons correctly. Such group
	  entries have been seen in the wild on FreeBSD.

	  Also, comment lines in group files are now ignored (also seen
	  on FreeBSD).

2013-10-14  Arthur de Jong <arthur@arthurdejong.org>

	* [0697347] common/dict.c: Use djb2 hash in dict module

	  This slightly modifies the string hashing function to use the
	  djb2 hash.  This hash is supposed to be reasonably fast and have
	  reasonably few collisions.

2013-10-07  Arthur de Jong <arthur@arthurdejong.org>

	* [61e96bf] nslcd/cfg.h: Increase NSS_LDAP_CONFIG_MAX_BASES to 31

	  This allows more search bases which may be useful in some
	  environments.

2013-09-15  Arthur de Jong <arthur@arthurdejong.org>

	* [2f088ec] common/tio.c: Also support poll() returning EAGAIN

2013-09-13  Arthur de Jong <arthur@arthurdejong.org>

	* [173d768] configure.ac: Add more python module checks to configure

	* [b7ca95a] configure.ac: Make missing Python modules a waring

	  This avoids having to have all modules installed in the build
	  environment. A Python version is still required during build.

	* [f36bb81] pynslcd/cache.py, pynslcd/group.py: Remove unneeded
	  imports

	* [8ae8b9a] Makefile.am, configure.ac, tests/Makefile.am: Cleanups
	  and fixes related to automake upgrade

	  This removes a few legacy workarounds and fixes for older versions
	  of automake. This also removes adding specific DEBUG flags for
	  tests since subdir objects are handled differently now.

	* [2bd2bc4] pam/pam.c: Initialise msg to avoid potential NULL
	  pointer dereference

	  The NULL pointer dereference in the PAM module should not occur due
	  to the relationship with the rc value that is handled alongside
	  it. This change mostly silences the compiler and protects from
	  future changes.

	* [dccc9cf] configure.ac: Add configure test for
	  {set,get,end}usershell() availability

2013-09-08  Arthur de Jong <arthur@arthurdejong.org>

	* [4fc4197] autogen.sh: Upgrade to automake 1.14

	* [bc6a18e] nslcd/nslcd.c: Use larger nslcd send buffers

	  By using bigger write buffers in nslcd we reduce the number of
	  writes in nslcd and consequently the number of reads in the NSS
	  and PAM modules for bigger responses.

	  This reduces the number of system calls that are made during
	  a request and brings a small performance improvement that is
	  mainly measurable in the NSS module. A measurement showed 30-80%
	  reduction in the number of system calls in the NSS module and
	  around 10% reduction in CPU usage (CPU time, only small reduction
	  in wallclock time).

	  Thanks John Sullivan for pointing this out.

	* [58d50bf] configure.ac, man/Makefile.am: Add configure check to
	  see whether to install manual pages

	  This also reworks the manual page generation check in the configure
	  script and avoids build errors if no tool for generating manual
	  pages is present when working on a Git checkout.

2013-09-04  Arthur de Jong <arthur@arthurdejong.org>

	* [ce95b41] ldapns.ldif: Reformat LDIF file to follow OpenLDAP format

	  This fixes a wrapping problem. Thanks to Paul Boven for pointing
	  this out.

2013-09-02  Arthur de Jong <arthur@arthurdejong.org>

	* [8b169f1] tests/test_common.c: Fix permissions of test
	  configuration

	  This sets the permissions on the nslcd-test.conf file while
	  running the tests to ensure that the permission checks for the
	  bindpwn and rootpwmodpw options do not fail the test.

	* [560e5de] .gitignore, tests/Makefile.am, tests/test_tio_timeout.c:
	  Add a test for tio timeout calculations

	  This test checks whether the proposed remaining time to sleep
	  is reasonable.

	* [db5382e] .gitignore, tests/Makefile.am, tests/test_clock.c:
	  Add a test for clock_gettime() supported clocks

	  This probes the system for available clocks to see if they can
	  be reliably used to get a monotonic-like timer (the test doesn't
	  verify the monotonic part, just usability).

	* [7895739] AUTHORS, common/tio.c, configure.ac: Use clock_gettime()
	  instead of gettimeofday()

	  This avoids problems with system clock changes (though there
	  are some safeguards in place to avoid waiting too long on clock
	  changes).

	  Thanks to John Sullivan for pointing this out.

	  We can't easily use CLOCK_MONOTONIC_RAW or CLOCK_MONOTONIC_COARSE
	  even on platforms that define the clock because we can get
	  runtime errors.  CLOCK_MONOTONIC seems to work on all tested
	  platforms that provide it.

	* [a683aa8] tests/test_manpages.sh: Small protability fix

	* [c8800eb] tests/test_manpages.sh: Improve robustness of
	  test_manpages

2013-08-31  Arthur de Jong <arthur@arthurdejong.org>

	* [644df52] common/tio.c, common/tio.h: Use normal timeout handling
	  in tio_skipall()

	  Use the same mechanism in tio_skipall() as in tio_read(), except
	  use a different timeout value.

	* [0787d45] common/tio.c: Refactor tio_wait()

	  This changes the function to accept a file descriptor, an event
	  and timeout parameter directly instead of a confusing flag.

	* [07a8170] common/tio.c: Fix buffer overflow on interupted read

	  The tio_read() function will read past its buffer and return
	  garbadge to the calling function if the call to read() was
	  interrupted by a signal.

	  The likelyhood of read() being interupted is low because previously
	  a call to poll() has determined that data is available to be read.

	  Thanks to John Sullivan for pointing this out.

	  See: https://bugzilla.redhat.com/show_bug.cgi?id=1003011

2013-08-30  Arthur de Jong <arthur@arthurdejong.org>

	* [4897033] nslcd/common.h: In nslcd, log EPIPE only on debug level

	  See: https://bugzilla.redhat.com/show_bug.cgi?id=1003011

	* [c9e2f97] common/tio.c, common/tio.h, nss/common.h: Use a timeout
	  when skipping remaining result data

	  When the NSS modules closes the connection and skips any remaining
	  result data, wait for up to 500 msec to read any available data.

	  See: https://bugzilla.redhat.com/show_bug.cgi?id=1003011

2013-08-27  Bersl <bersl2@bersl2.info>

	* [7140d21] AUTHORS, nslcd/group.c, nslcd/passwd.c, nslcd/shadow.c:
	  Increase password buffer size

	  With the smaller buffers some password hashes would be truncated.

2013-08-28  Arthur de Jong <arthur@arthurdejong.org>

	* [8571bc1] NEWS, README, common/dict.c, compat/attrs.h,
	  compat/nss_compat.h, man/nslcd.conf.5.xml, nslcd/myldap.c:
	  Fix for common spelling mistake

2013-08-25  Arthur de Jong <arthur@arthurdejong.org>

	* [890d227] AUTHORS, ChangeLog, NEWS, configure.ac,
	  man/chsh.ldap.1.xml, man/getent.ldap.1.xml, man/nslcd.8.xml,
	  man/nslcd.conf.5.xml, man/pam_ldap.8.xml, man/pynslcd.8.xml:
	  Get files ready for 0.9.1 release

	* [f9b4b43] Makefile.am: Have a nicer way of generating the ChangeLog

	  This adds the commit id, improves the line wrapping and also
	  gets rid of the external dependency.

	* [321d8a3] pynslcd/pynslcd.py: Handle failure of getpeercred
	  more gracefully

	* [f18729e] tests/Makefile.am: Only run pynslcd tests if it
	  is enabled

	* [f54f2ad] configure.ac, m4/ax_python_module.m4: Add configure
	  test for Python modules

	  This uses the AX_PYTHON_MODULE test to check for availability
	  of used Python modules. All third-party modules and modules that
	  are not a builtin for Python 2.5 are tested.

	  This also splits the tests for the utils and pynslcd.

	* [6f61482] pynslcd/attmap.py, pynslcd/group.py, pynslcd/pynslcd.py,
	  pynslcd/tio.py, utils/getent.py, utils/nslcd.py: Rearrange
	  Python imports

2013-08-23  Arthur de Jong <arthur@arthurdejong.org>

	* [f6c20ee] nslcd/nslcd.c: Ignore SIGUSR2 for future compatibility

	* [27abbbb] man/Makefile.am, tests/Makefile.am,
	  tests/test_manpages.sh: Add a test for the manual pages

	  This replaces e0491d2 to run xmlto from the man directory. This
	  handles the case more gracefully if xmlto is not available.

2013-08-18  Arthur de Jong <arthur@arthurdejong.org>

	* [494833d] config.guess, config.sub: Update files from latest
	  automake

2013-08-21  Arthur de Jong <arthur@arthurdejong.org>

	* [7b474d0] pynslcd/group.py, pynslcd/passwd.py, pynslcd/shadow.py:
	  Have pynslcd handle mapped userPassword

	  This fixes an error that could occur when the userPassword was
	  retrieved from LDAP and insufficient privileges were available
	  for reading the attribute.

	* [b0358f7] : Retry LDAP servers quickly after receiving SIGUSR1

	  When nslcd receives the SIGUSR1 signal it will retry connecting
	  to unavailable LDAP servers sooner.

	  This signal can for example be sent when (re)stablishing a
	  network connection.

2013-08-20  Arthur de Jong <arthur@arthurdejong.org>

	* [ebbe8a6] man/nslcd.8.xml, nslcd/nslcd.c: Handle SIGUSR1 by
	  resetting the retry timer

	  This implements and documents handling of the SIGUSR1 signal in
	  nslcd to reset the reconnect_sleeptime and reconnect_retrytime
	  timers to re-check availability of the LDAP server.

	* [8bdb289] nslcd/myldap.c, nslcd/myldap.h: Implement function
	  for resetting reconnect times

	  This implemens a myldap_immediate_reconnect() function that
	  resets the reconnect timer to retry failing connections to the
	  LDAP server upon the next search.

	  This can be used to cut the reconnect_sleeptime and
	  reconnect_retrytime sleeping periodss short if we have some
	  indication that the LDAP server is available again.

	* [d58f163] nslcd/common.h, nslcd/nslcd.c, nslcd/shadow.c: Return
	  partial shadow information to non-root users

	  This also returns everything except the password hash from
	  the shadow database to non-root users (nothing was returned
	  before). This allows non-root users to do PAM authentication in
	  some configurations.

	  On some systems there is a setgid executable that is allowed to
	  read /etc/shadow for authentication by e.g. screensavers. Returning
	  no shadow information will cause pam_unix to deny authorisation
	  in common configurations.

	  See: http://bugs.debian.org/706913

	* [34365b4] nslcd/cfg.c: Add cast to int when logging configuration
	  summary

2013-08-18  Arthur de Jong <arthur@arthurdejong.org>

	* [44a38eb] pam/pam.c: Small fix in NEW_AUTHTOK_REQD handling

	  There is a potential memory leak if the old password is saved
	  multiple times. Furthermore, PAM_NEW_AUTHTOK_REQD is only allowed
	  as a result of the authorisation phase, not the authentication
	  phase so there is no use in checking.

	* [d8637bb] pynslcd/pam.py: Fix rootpwmodpw handling in pynslcd

	* [13d31b7] pynslcd/common.py: Fix not logging passwords in pynslcd
	  (7108b1f)

	* [7e90541] tests/nslcd-test.conf, tests/test.ldif: Update files
	  from test environment

2013-07-29  Arthur de Jong <arthur@arthurdejong.org>

	* [724a75f] utils/getent.py: Improve error and help output of
	  getent command

2013-08-18  Arthur de Jong <arthur@arthurdejong.org>

	* [882f7be] tests/Makefile.am, tests/pylint.rc, tests/test_pylint.sh:
	  Run pylint as a test

	  This runs a somewhat limited pylint run against the source
	  files. It should at least catch some issues.

	* [79209ee] pynslcd/common.py, pynslcd/group.py, pynslcd/pam.py,
	  pynslcd/passwd.py: Rename isvalidname() to is_valid_name()
	  in pynslcd

2013-08-10  Arthur de Jong <arthur@arthurdejong.org>

	* [e0491d2] man/Makefile.am: Run xmlto on manual pages as part of
	  the tests

2013-08-18  Arthur de Jong <arthur@arthurdejong.org>

	* [7108b1f] pynslcd/common.py: Do not log passwords in pynslcd

	* [cda6dcd] : Implement an option to run in the foreground

	  This introduces a -n, --nofork option that skips the deamonising
	  step on start-up. This may be required for running nslcd from
	  upstart.

	  See: https://bugs.launchpad.net/bugs/806761

	* [1825be6] man/nslcd.8.xml, man/pynslcd.8.xml: Document -n,
	  --nofork option

	* [82bcfd7] pynslcd/pynslcd.py: -n switch for pynslcd

2013-08-17  Caleb Callaway <enlightened.despot@gmail.com>

	* [14b93b9] nslcd/nslcd.c: -n switch for nslcd (prevents process
	  from forking)

2013-08-17  Arthur de Jong <arthur@arthurdejong.org>

	* [8a3f0f5] : Improvements to pynslcd caching functionality

	  This fixes most of the existing caching functionality. Cache
	  expiry, negative hits and entries going away remain to be
	  implemented.

2013-08-16  Arthur de Jong <arthur@arthurdejong.org>

	* [a066bcb] configure.ac, tests/Makefile.am,
	  tests/test_pynslcd_cache.py: Implement tests for caching
	  functionality

2013-08-12  Arthur de Jong <arthur@arthurdejong.org>

	* [d66162a] pynslcd/alias.py, pynslcd/cache.py, pynslcd/group.py,
	  pynslcd/host.py, pynslcd/netgroup.py, pynslcd/network.py,
	  pynslcd/protocol.py, pynslcd/rpc.py, pynslcd/service.py: Use
	  retrieve_by, group_by and group_columns in the cache

	  This removes custom retrieve() functions and Query classes from
	  the database modules and uses retrieve_sql retrieve_by, group_by
	  and group_columns to make a custom retrieval query.

	  In the cache module this completely replaces how the query grouping
	  is done. The Query class is now only used inside the cache and the
	  CnAliasedQuery, RowGrouper and related classed have been removed.

2013-04-23  Arthur de Jong <arthur@arthurdejong.org>

	* [bfe22cc] pynslcd/cache.py: Make Cache a context manager

2013-08-12  Arthur de Jong <arthur@arthurdejong.org>

	* [1b89df5] pynslcd/alias.py, pynslcd/cache.py, pynslcd/group.py,
	  pynslcd/host.py, pynslcd/netgroup.py, pynslcd/network.py,
	  pynslcd/protocol.py, pynslcd/rpc.py, pynslcd/service.py: Give
	  cache tables friendlier names

	  This also defined the tables for netgroup storage.

2013-08-11  Arthur de Jong <arthur@arthurdejong.org>

	* [7671276] pynslcd/alias.py, pynslcd/cache.py, pynslcd/group.py,
	  pynslcd/host.py, pynslcd/network.py, pynslcd/protocol.py,
	  pynslcd/rpc.py, pynslcd/service.py: Explicitly define tables
	  used for cache

	  This introduces the tables property in the Cache object that is
	  used to define the used tables.

	  This also fixes the storing of mulit-valued attributes in
	  the cache.

2013-04-16  Arthur de Jong <arthur@arthurdejong.org>

	* [b0b5723] pynslcd/alias.py, pynslcd/cache.py, pynslcd/ether.py,
	  pynslcd/group.py, pynslcd/host.py, pynslcd/netgroup.py,
	  pynslcd/network.py, pynslcd/passwd.py, pynslcd/protocol.py,
	  pynslcd/rpc.py, pynslcd/service.py, pynslcd/shadow.py: Move
	  cache table creation to modules

	  This also moves the creation of a SQLite database connection to
	  a _get_connection() function to ensure the cache is only created
	  when the caches are instantiated.

2013-07-30  Arthur de Jong <arthur@arthurdejong.org>

	* [84d22e6] pynslcd/passwd.py: Fix missing part of d659e83

2013-07-29  Arthur de Jong <arthur@arthurdejong.org>

	* [ec53918] pynslcd/group.py, pynslcd/passwd.py: Use cleaner import
	  and get rid of uid2dn function in pynslcd

	* [d659e83] pynslcd/cfg.py, pynslcd/passwd.py: Handle the nss_min_uid
	  option in pynslcd

	* [7092d40] pynslcd/cfg.py, pynslcd/group.py: Handle the
	  nss_initgroups_ignoreusers option in pynslcd

	* [a0e12e6] pynslcd/cfg.py, pynslcd/pam.py: Fix handling of
	  pam_password_prohibit_message in pynslcd

	* [fa97bcc] pynslcd/Makefile.am, pynslcd/config.py,
	  pynslcd/pynslcd.py: Implement config request handling in pynslcd

	  This allows the PAM module to request the
	  pam_password_prohibit_message option for denying password change.

	* [a3acbec] pynslcd/pam.py: Implement PAM session handling in pynslcd

	  Just like in nslcd this doesn't actually do anything with the
	  session ids except generating them.

2013-07-26  Arthur de Jong <arthur@arthurdejong.org>

	* [4031750] pynslcd/search.py: Properly handle start_tls in pynslcd

2013-07-27  Arthur de Jong <arthur@arthurdejong.org>

	* [5d3f681] configure.ac: Have configure show --disable-utils
	  by default

	  Since the utils are automatically built if Python is available
	  --disable is more appropriate a default then --enable.

	* [5adc2ca] tests/test_pycompile.sh: Have test_pycompile not write
	  any pyc files

	  We need to avoid writing pyc files because during make distcheck,
	  the source directory is read-only.

	  This also ensures that the test is skipped if the Python
	  interpreter is not found.

	* [e17730f] README: Dcoumentation updates

	  This fixes a typo, clarifies the section on the LDAP schema
	  values that are supported and updates the differences between
	  nss-pam-ldapd and nss_ldap and pam_ldap.

2013-07-26  Arthur de Jong <arthur@arthurdejong.org>

	* [30ffdb2] tests/Makefile.am, tests/test_pycompile.sh: Test Python
	  syntax on make check

	* [10eec70] : Merge fixes for reconnect_invalidate option

	  The branch accidentally got merged before it was fully tested.

	* [dce98a5] nslcd/cfg.c, nslcd/invalidator.c, pynslcd/invalidator.py,
	  pynslcd/pynslcd.py: Fix errors in invalidator changes

	  This fixes a few typos and an omission in the configuration file
	  parsing code.

	* [7c85202] : Make cache invalidation more generic

	  This changes the nscd_invalidate option into a more generic
	  reconnect_invalidate and also allows clearing the nfsidmap cache.

	* [e1b0399] man/nslcd.conf.5.xml, nslcd/Makefile.am, nslcd/cfg.c,
	  nslcd/cfg.h, nslcd/common.h, nslcd/invalidator.c, nslcd/myldap.c,
	  nslcd/nscd.c, nslcd/nslcd.c, pynslcd/Makefile.am, pynslcd/cfg.py,
	  pynslcd/invalidator.py, pynslcd/nscd.py, pynslcd/pynslcd.py,
	  pynslcd/search.py, tests/Makefile.am: Rename nscd_invalidate
	  option to reconnect_invalidate

	  This also renames the internal nscd module to invalidator for
	  both nslcd and pynslcd. The new invalidator module is now no
	  longer nscd-specific.

	* [6054499] man/nslcd.conf.5.xml, nslcd/attmap.c, nslcd/cfg.c,
	  nslcd/cfg.h, nslcd/nscd.c, pynslcd/cfg.py, pynslcd/nscd.py:
	  Allow invalidating the nfsidmap cache

	  This introduces an nfsidmap value for nscd_invalidate which will
	  cause the nfsidmap -c command to be run.

2013-07-17  Arthur de Jong <arthur@arthurdejong.org>

	* [d2e2e40] pynslcd/nscd.py: Fix nscd cache flushing bug in pynslcd

	  The pynslcd implementation would always clear the passwd nscd
	  cache regardless of the provided map.

	  utils/chsh.py, utils/getent.py, utils/nslcd.py, utils/users.py:
	  Python style changes

	  This tries to conform more closely to PEP8. Imports have been
	  checked and, if used only once, moved closer to the use to avoid
	  potential import loops. This also includes a few other minor
	  changes, like using __main__ for utility scripts and variable
	  renames to avoid name clashes.

	* [d3c6a66] pynslcd/pam.py: Raise an error with a missing old
	  password on password modification

	* [f45b24d] utils/nslcd.py: Set FD_CLOEXEC on the client socket
	  in utilities

	* [bc35197] pynslcd/pam.py: Fix getting caller's uid on password
	  change (pynslcd)

2013-04-06  Arthur de Jong <arthur@arthurdejong.org>

	* [84402e5] utils/Makefile.am: Install utilities in share/nslcd-utils

	* [b5b4239] man/Makefile.am: Fix the way manual pages are installed

	  The :u flag apparently isn't portable across versions of make
	  and automake rules complain if a manual page is added twice to
	  a target.

2013-04-03  Arthur de Jong <arthur@arthurdejong.org>

	* [1c31305] configure.ac: Ignore missing Python in initial test

	* [4b01125] nslcd/nslcd.c: Fix comment

2013-03-30  Arthur de Jong <arthur@arthurdejong.org>

	* [d7990de] pynslcd/pam.py: Update the shadowLastChange on password
	  change in pynslcd

	* [ea6bff3] pynslcd/pam.py: Implement password modification
	  in pynslcd

	* [62a409c] : Implement used modification functionality

	  This adds user information modification functionality to nslcd
	  and pynslcd and implements a chsh.ldap utility that can be
	  used to change the login shell of a user (similar to the normal
	  chsh command).

	  The user modification functionality should allow for generic
	  modifications of user information. More utility commands to
	  perform modifications remain to be implemented.

	* [012b185] .gitignore, man/Makefile.am, man/chsh.ldap.1.xml,
	  utils/Makefile.am, utils/chsh.py, utils/cmdline.py, utils/nslcd.py,
	  utils/shells.py, utils/users.py: Initial version of a chsh.ldap
	  utility

	* [d0482fb] pynslcd/pynslcd.py, pynslcd/usermod.py: Handle user
	  modification requests in pynslcd

	  Similar to the nslcd implementation, this currently only covers
	  modifying the homeDirectory and loginShell attributes.

	* [f1895f9] nslcd/Makefile.am, nslcd/common.h, nslcd/nslcd.c,
	  nslcd/usermod.c: Handle user modification requests in nslcd

	  This is currently limited to supporting modification of the
	  homeDirectory and loginShell attributes.

	  Modifications as root currently use the rootpwmoddn and rootpwmodpw
	  options.

	* [8fb5eb1] nslcd.h: Define a NSLCD_ACTION_USERMOD request

	  The modification can either be requested by root or by the
	  user itself.

	  Modifications by the user should be done by connecting to the
	  LDAP server with the user-supplied credentials. It is expected
	  that access controls in the LDAP server prevent unwanted
	  modifications. The nslcd process is expected to check whether
	  supplied values are sensible.

	* [aae36cf] pynslcd/pam.py: Rename authentication function and
	  return connection

	* [355c2af] configure.ac: Fix test for absence of Python

	* [f478830] pynslcd/cfg.py: Mark unsupported pynslcd configuration
	  options

	* [2b097f7] configure.ac: Preset default configure values
	  consistently

	* [6ceb1df] configure.ac: Give an error when the Python interpreter
	  is missing

2013-03-29  Arthur de Jong <arthur@arthurdejong.org>

	* [a47b20f] configure.ac: Build command-line utilities by default
	  if Python is available

	* [adde1d4] : Implement clearing of nscd cache in pynslcd

	* [a75cfb9] pynslcd/nscd.py, pynslcd/search.py: Detect and handle
	  connection failure and recovery

	  Logs a connection recovery message and run a nscd cache
	  invalidation if configured.

	* [585d388] pynslcd/pynslcd.py: Start the nscd invalidator process
	  if needed

	* [d4c5c96] pynslcd/cfg.py: Parse the nscd_invalidate option

	* [11b1739] pynslcd/Makefile.am, pynslcd/nscd.py: Functionality
	  for clearing the nscd cache in pynslcd

	* [65a65ad] pynslcd/pynslcd.py: Switch to using os.environ instead
	  of os.putenv()

	  The os.putenv() call doesn't update os.environ and Python
	  documentation recommends using os.environ.

	* [46cf240] pynslcd/pam.py: Rename validate_request to validate

	* [7d1e492] pynslcd/pam.py: Also perform authentication search
	  using LDAPSearch class

2013-03-28  Arthur de Jong <arthur@arthurdejong.org>

	* [302c2fa] tests/test_nsscmds.sh: Make the NSS tests dependant
	  on the configuration of nsswitch.conf

	* [8790b40] tests/test_myldap.c: Do not rely on printf() being
	  able to print NULL strings

2013-03-24  Arthur de Jong <arthur@arthurdejong.org>

	* [932c641] man/nslcd.conf.5.xml: Fix manual page generation

	* [07ca836] nslcd/cfg.h: Fix comment for nss_nested_groups config
	  option

	* [3daa68d] : Implement support for nested groups

	* [642064c] tests/test.ldif, tests/test_nsscmds.sh: Add tests for
	  nested group functionality

	  This also includes some changes to the test directory contents
	  that were for other tests and functionality.

	* [b1b7648] README, man/nslcd.conf.5.xml, nslcd/cfg.c, nslcd/cfg.h,
	  nslcd/group.c, pynslcd/cfg.py, pynslcd/group.py: Implement a
	  nss_nested_groups configuration option

	  This option can be used in both nslcd and pynslcd to enable
	  recursive group member lookups. By default the functionality is
	  disabled. This also updates the documentation.

	* [d6a6e8b] pynslcd/common.py, pynslcd/group.py: Implement support
	  for nested groups in pynslcd

	* [41ba574] nslcd/group.c: Implement support for nested groups
	  in nslcd

	  This differs from the code provided by Steve Hill in that it avoids
	  (recursively) performing parallel LDAP searches by queueing groups
	  and check for extra members per queued group (in the forward
	  lookup) or check for extra parents (for the user to groups lookup).

	  For the reverse lookup handling the NSLCD_HANDLE macro could no
	  longer be used because extra care should be taken to free the
	  sets before returning and two search phases are needed.

2013-03-20  Steve Hill <steve@opendium.com>

	* [08f5301] AUTHORS, nslcd/group.c: Implement a
	  mkfilter_group_bymemberdn() function

	  This was part of a bigger change to implement nested groups,
	  however most of the other parts were re-implemented differently.

	  For the original changes, see:

	* [f21efd6] nss/common.h: NSS: Return TRYAGAIN on zero-length buffer

	  One of our customers was running into a situation where glibc
	  provided a zero buffer, which is a condition that is retriable
	  and the nss module should return NSS_STATUS_TRYAGAIN not
	  NSS_STATUS_UNAVAIL.
