Environment
GroupWise Messenger 18
Situation
Some users are able to log into Messenger, others are not.
In the Messenger client, getting an error: The server has experienced a directory error.
In the NMMA log file, seeing: Login failed [0xAD43]: <username> - Unable to establish connection with LDAP server
The users that are able to log into Messenger have their Messenger account linked to their GroupWise account while the users that are unable to log in do not have their accounts linked.
Resolution
GroupWise Messenger 18 requires the authentication request to be made through the GWLDAP service.
Therefore, if users are required to authenticate through LDAP, the Messenger and GroupWise accounts need to be linked.
