The "title" attribute for the user referenced in the error on the publisher exceeds the number of characters allowed for the "title" attribute on the subscriber. This is due to different schema versions of Active Directory.
On the Publisher edit the user object and decrease the number of characters entered in the "Title" to a value that is allowed on all subscribers then re-publish the collection.
More information on the Title Attribute for different versions of Active Directory can be found on the MSDN Active Directory Schema page for the "Title" attribute
