Increase log level to Trace and reproduce the issue
Tested the new server settings-account with AD explorer - OK to access and navigate to user.
Collected logs from the error:User '' bind failed with domain 'global.avaya.com' Reason:Xxx.yyy.zzz.ddd
From the :3269 - We can see the global catalog is rejecting the configuration.
After remove the global catalog (No need in this new LDAP configuration) XM Server is able to configure an LDAP connector succesfully
