When attempting to set up or change LDAP settings (or point to another LDAP server in case of disaster recovery testing), using the "Test LDAP Connection" throws an AwE-5008 error with additional details:
LDAP authentication error
The LDAP server being used is the fully qualified domain name and has been confirmed. Everything else is set up as expected and exactly the same as in a working environment, only the LDAP server has changed.
Check the DNS configuration. Using something from the server where Applications Manager (the RMI Server/Master agent) is installed, run a command:
ping [LDAP server name]
or
telnet [LDAP server name] [LDAP port]
If the ping or telnet does not go through and throws an error, try to use the LDAP server's IP address instead. If a ping or telnet of the IP does not work, you will need to talk to your LDAP admins and network admins to find out why and resolve the issue.
