Appendix: Global catalog for Connect and Presence
The global catalog is a distributed data repository that contains a searchable, partial representation of every object in every domain in a multi-domain Active Directory Domain Services (AD DS) forest. Global catalogs are typically used in a single AD DS forest that has more than one domain. A global catalog provides a way for products and services to access data that is available in other domains in the same forest. For more information about global catalogs, visit the Technet Library to see What Is the Global Catalog?.
You can configure the
Connectservice to use the global catalog so that the
Connectservice can find users who exist in other domains within your AD DS forest. This enables the
BlackBerry Connectapp to search for people in those other domains and start conversations with them, or add them to the contact list.
You can also configure the
Presenceservice to use the global catalog so that the
Presenceservice can subscribe the receive presence information for
Skype for Businessusers who exist in other domains within your AD DS forest. This is helpful if you are using a
Presenceclient, such as
BlackBerry Work, by users who email with others who reside in other domains in your AD DS forest.
In addition to configuring the
Presenceservices to use the global catalog, you must replicate some additional
Skype for Businessattributes to the global catalog. You must perform this set up only once, whether the global catalog is used for one or both services. Some environments might require some
Active Directoryattributes to be correctly replicated to the global catalog in the other domains. For more information about enabling replication of user attributes to the global catalog server, visit support.blackberry.com/community to read article 46152.
