Hello: I've got the Windows Sync service set up to sync with an AD server. For some unknown reason, several of the groups on the AD server have an email address and the mail:, the mailNickname: and several exchange-related attributes set. How would I go about modifying the schema that the Windows Sync service is using to create the groups on the DS side of things? I believe adding the mailrecipient object class should do the trick, but I can't find any documentation on doing this. Alternately, if there's a way of just dropping incompatible attributes when syncing, that would work too. The error I currently get when syncing: Entry "cn=Support,ou=Groups, dc=example, dc=com" -- attribute "mail" not allowed NSMMReplicationPlugin - add operation of entry cn=Support,ou=Groups, dc=example, dc=com returned: 65 Any suggestions would be helpful! - Jonas
