Configuring Kerberos Environment / Kerberos Requirements |
With Kerberos, it is essential that the time is synchronized between all of the computers on the network.
The maximum time difference that is permitted between servers, clients, and the KDC is 5 minutes (by default). Servers, clients, and the KDC must have theirs time well synchronized.
Check all of them and verify the time is synchronized within 5 minutes for all servers, clients, and the KDC.
