[Samba] Printer desappeared... configuration and backup?

[Marco Gaiarin]

Samba AD domain, composed of different DCs and DMs, someone used (also) as print
server with CUPS, with Point'n'Print (driver loaded server side).


This morning in a site all printers but 1 'desappeared': really the don't desappear,
simply the association between printers and driver get lost someway, so
printer come back to standard CUPS printer name, so clients say that printer
desappeared.

I've simply re-associated driver to printers, using the previous printer
names, and all user get back in job.


But...

1) i've not found the root cause of that; there's some hint/keyword i can
 try to grep in logs to have some clue?

2) i've not found the config file or 'TDB' that contain printer
 configuration; i remembered something like that happened when i used NT domain, but
there's a 'printer.tdb' (or something like that) that contain all the conf,
so backing up and putting in place the correct file suffices.

Where are saved printers association with driver, printer names and
generally printer configuration in an AD domain? Directly in AD?


Thanks.
