Synchronizing Attributes in Cross Forests for Lync Server 2010

Lync Server 2010
 

Topic Last Modified: 2011-03-02

If your organization deployed Microsoft Exchange Server 2007 in a cross-forest topology, you must implement synchronization of the following attributes for Lync Server 2010 when deployed in a central forest.

If Lync Server 2010 is deployed in a central forest, the same attributes need to be synchronized for the contact object in the central forest.

You must also synchronize the mailbox in the Microsoft Exchange Server forest.

The following attributes must be synchronized from the user object to the contact object.

  • ObjectSid
  • telephoneNumber
  • displayName
  • givenName
  • sn (surname)
  • physicalDeliveryOfficeName
  • l (city)
  • st (state)
  • Country
  • Title
  • Mail
  • Company
  • Cn
  • thumbnailphoto
  • manager
  • Department

The following table shows how attributes are mapped from a user object to a contact object using the example user, User A.

For group–to-contact synchronization, the attribute msDS-SourceObjectDN on the contact should be populated with the DN of the group that is used in the forest where the group is managed.
