After Parallel upgrade, you get this error, it still works as expected in Legacy but fails in the New IDM setup.
The error we see in LDAP is CN is not getting updated, hence the error.

Release : 14.4
Component : IdentityMinder(Identity Manager)
In one of the new14.4 environments the FullName LAH was apparently not firing even though it appeared to be enabled in the Management Console. It works fine another 14.4 environment. There may be some corruption in the LAH definition in the Object Store.
Restart the Environment.
