[Samba] BDC problem!? user can't get profile/map drive

Top posting is bad...

While that is a fine THEORY, when the machine that holds the data is 
dead your profile is still missing.  If you simply point to another 
server all you're going to get is either old crusty data from the last 
time your PDC was unavailable or no data at all.  What I would suggest, 
is another machine that holds this data for you. 

If you want, you could have it sharing the data via NFS to your samba 
machines, or point directly to the machine as a samba member server that 
holds the data for the path of the drives as opposed to %L.
