I'm still trying to get my evaluation copy of Red Hat Directory Server 7.1SP3 to sync with Windows Active Directory. The latest hitch is an error message following an initial re-synchronization attempt. The Directory Server has a few hundred users imported from a Windows NT domain. The Active Directory server has none of those users, so the initial re-sync should add them to AD. The error occurs when Windows Sync tries to add the first user entry to the Active Directory. The message is: Attempting to add entry cn=John Doe,ou=Domain Users,dc=ad,dc=example,dc=com to AD for local entry uid=jdoe,ou=people,o=ourorg.com Followed by: (ADserver:636): Received result code 21 (00000057: LdapErr: DSID-0C090B38, comment: Error in attribute conversion operation, data 0, vece) for add operation I would appreciate any insight. Hoping to see if this actually works before the 30-day evaluation runs out. Thanks. -Glenn.
