[Samba] ads_kinit_password failed: Preauthentication failed

[Aaron Kincer]

Lachlan,

One more thing--make sure that your Samba server and your domain servers 
are in step with the correct time (NTP helps). If your Samba server 
attempts to authenticate against the domain and doesn't have the correct 
time, authentication can (and usually does) fail from what I've seen 
with ADS on Windows 2003 (native mode).

I run into that problem occasionally when for one reason or another, 
RHEL decides to stop polling NTP to update the time and loses time (RHEL 
on VMWare is screwy BTW).

Hope that helps.
