Clock skew too great for Kerberos authentication

The time difference between the BMC Atrium Single Sign-On server and the Key Distribution Center (KDC) (or ActiveDirectory domain controller) is too great. Normally, the time difference should be no great than 5 minutes. Use a time server to synchronize the computers or adjust the time manually to be closer in sync.

Error: javax.security.auth.login.LoginException(3):Clock skew too great (37)
