4.3Synchronizing the Device and Server Time
If you configure an authentication server or address book server for Kerberos authentication, you must ensure that the device clock and server clock are synchronized within the maximum server specified clock skew tolerance of ‘5’ minutes. When you authenticate using Kerberos, if there is more than a 5 minute time difference between the device clock and server clock, an error message is displayed.
You can manually adjust the device time to synchronize with the server time, or you can set to automatically synchronize the device clock with the server clock.
4.3.1Specifying Automatic Time Synchronization
You can set the SNTP (Simple Network Time Protocol) settings to enable the device to automatically synchronize its system time with a public time server.
