KeyError during update of media

[st31ny]

When a user is removed from an LDAP group but orphans are not deleted, the subsequent media update tries to access a user that does not exist:

zabbix-ldap-sync/lib/zabbixconn.py

Line 588 in 02412a9

if self.ldap_conn.get_user_media(ldap_users[each_user], self.ldap_media):

Here, each_user is an element of zabbix_group_users which might contain users who are not present in the LDAP group anymore but have not been deleted before (in

zabbix-ldap-sync/lib/zabbixconn.py

Line 536 in 02412a9

absent_users = set(zabbix_group_users) - set(list(ldap_users.keys()))

).
