This configuration parameter enables Kerberos to automatically correct for a time difference between the system clock and the clock used by the KDC. You only need to set this parameter if your system clock is drifting and the system is not using NTP and adclient SNTP settings.
In most cases, you set this configuration parameter using group policy.
You can, however, set it manually in the configuration file if you are not using group policy or want to temporarily override group policy.
If this parameter is not defined in the configuration file, its default value is false.
