User Management Overview
------------------------

Users are added to VOSS-4-UC from these potential sources:

* Synchronized from LDAP
* Synchronized from Cisco Unified Communications Manager
* Bulk loader template
* Manually created

Typically, users are associated with a site. You can create move filters to
automatically assign users to sites when they are synchronized from LDAP or
Unified CM. Bulk loaded and manually created users can be moved using filters or
by individually selecting users.

There are two categories of users, local administrators and end users. The
local administrators can be assigned to any of the hierarchy nodes
(provider, customer, site). End users can only be assigned at the site level.

If an Identity Provider server is deployed at a hierarchy node above the site,
you can configure VOSS-4-UC to provide Single Sign-On support for users created
or synchronized at that hierarchy node.

Conflicts between users synchronized from different sources are handled according
to the strategy described in :ref:`managing_duplicate_usernames`. For information about
user password management, depending on the source of the user, see Password Management.

Users associated with a site can be pushed to the Unified CM that appears in the
Network Device List assigned to that site. Once pushed to Unified CM, users become
subscribers that can be provisioned with various collaboration services.

If a user's language is not explicitly set, the language is inherited from the
nearest hierarchy node (at or above the user node) that has a default language.
If no default language is set anywhere in the hierarchy at or above the user node,
the language is set to English.
