[Samba] WinY2k Access Denied on Printing

[adam at morrison-ind.com]

I have a Red Hat Linux release 7.1 (Seawolf) Samba 2.2.4 PDC and fileserver
built with --with-ldapsam.  The clients are either win9x or WinY2k. 
Authenitcation, etc... all works great.

But print sharing is a real pain.  Under 2.2.1a printing worked great,  but our
VOIP phone system wouldn't joint the domain until we upgraded to 2.2.4.  Initial
testing of 2.2.4 made it seem like everything worked.  But eventually WinY2k
users can't print, they simply get access denied.  If they remove the printer
and re-add they can't print for a little while before it goes back to access denied.

ANY assistance would be greatly appreciated.
