Synchronize the Clock

For Kerberos to work properly, your system clock must be synchronized with the server clock that you are connecting to.  If for some reason your clock is not in synch with the Kerberos server time, you may receive an error message stating that your system clock needs to be set or synchronized with the network server. If you are running Mac OS X 10.4 or higher, follow these steps to synchronize your machine clock to the server.

1. Click the Apple menu and select System Preferences.
2. From the System Preferences window, select Date & Time under the System area.
3. Select the Date & Time tab.
4. Verify that the Set date & time automatically option is selected and type ntp.net.cmu.edu in the drop-down field.
5. Close the Date & Time window.
