Connection to multiple LDAP servers

[mkk1001]

Hi, how to connect RabbitMQ to two or more ldap servers (different domains)?

My configuration:

auth_backend.1 = internal
auth_backend.2 = ldap
auth_ldap.servers.1 = domain1.example.local
auth_ldap.timeout   = 10000
auth_ldap.port = 636
auth_ldap.use_ssl = true

It works for me
If I add another server auth_ldap.servers.2 = domain2.example.local, i cant login

I tried use ${ad_domain} in config auth_ldap.servers.1 = ${ad_domain}.example.local , this does not work

rabbitmq ver.3.8.26

Your configuration file is mis-formatted. Please see the docs - https://www.rabbitmq.com/ldap.html#connectivity

Note the . in use as a separator, not a _ character:

auth_backend.1 = internal
auth_backend.2 = ldap
auth_ldap.servers.1 = domain1.example.local
auth_ldap.servers.2 = domain2.example.local
auth_ldap.timeout   = 10000
auth_ldap.port = 636
auth_ldap.use_ssl = true

Using a substitution like ${ad_domain} is not supported in the rabbitmq.conf file.

I'm sorry my mistake.I have corrected the config in question

With this configuration, rabbitmq only sends requests to one server.
If i login [email protected] request to domain2.example.local
why rmq not use all ldap.servers ?

When you specify multiple servers, it is used to round-robin connections and to provide a backup in case a connection fails. RabbitMQ and the LDAP plugin do not distinguish between servers based on the login credentials passed to the LDAP plugin.
