Figure 84 Confirming NTPServer Synchronization
To synchronize with a Network Time Protocol server, the Synchronize time with NTP server check box

In the example shown in Figure 84, the W-ClearPass Policy Manager server is synchronized to two NTP
servers on the Internet.
3. Return to the Server Configuration page by clicking Cancel.
4. Compare the clock time displayed at the bottom of the W-ClearPass Server Configuration page against
the clock time on the Active Directory server.
The maximum allowed clock skew between the W-ClearPass server and the Active Directory server is five minutes.
5. If the time on the two systems doesn't exceed the clock skew limit, then proceed.

To join a W-ClearPass server to an Active Directory domain:
1. In the Server Configuration screen, click the name of the W-ClearPass server that you want to join to
the domain.
The Server Configuration screen for the selected server opens.
