# Remote Authentication

Command Center supports configuring connections to external user directory
services.

After defining a connection to an external directory service, users in that
directory service can be imported into Command Center and assigned relevant
roles governing their access privileges.
See [Importing users from an external directory](ccvm-users.md#ccvm-importing-external-directory-users) and
[Roles](ccvm-roles.md#managing-command-center-roles).

## Viewing directory service connections

1. At the top right of the Command Center window, click the gear icon.
2. In the dropdown menu that displays, select **Remote Authentication**.

   The Remote Authentication screen displays the directory service
   connections.
