Fire up system-configure-date and use the AD server as your clock source, or edit the files in /etc/ntp and put it in there. BTW, it's best if you use the AD server as your sole clock source, as the Windows authentication stuff is based on Kerberos and uses the date and time as part of the ticket generation. If the Linux box gets out of sync by as little as 5 minutes (300 seconds), authentication won't work. ---------------------------------------------------------------------- - Rick Stevens, Principal Engineer rstevens@xxxxxxxxxxxx - - VitalStream, Inc. http://www.vitalstream.com - - - - Reality: A crutch for those who can't handle science fiction - ----------------------------------------------------------------------
