.. _20.1.1|VOSS-551|EKB-4393:

There are two types of users in VOSS-4-UC:

===================== =========================================================================
Local administrators  Can be assigned to any of the hierarchy nodes (provider, customer, site).
End users             Can only be assigned at the site level. 
===================== =========================================================================


.. important::

   For VOSS-4-UC release 21.1, refer to the *VOSS-4-UC 21.1 Release Changes and Impact*
   PDF document on the Documentation Portal for details on model and workflow changes. Customizations related to these
   changes may be affected.


.. rubric:: How Users are Added to the System

Users may be added to VOSS-4-UC from these sources: 

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


Users are typically 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.

If an identity provider (IdP)server is deployed at a hierarchy node above the site,
you can configure VOSS-4-UC to provide single sign-on (SSO) support for users created
or synchronized at that hierarchy node.

.. note:: 

   (Cisco only) 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.


.. rubric:: User Sync Conflicts

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.




.. rubric:: User Default Language

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.
