[Samba] rpcclient enumdrivers fails with WERR_UNKNOWN_PRINTER_DRIVER

[Urs-Jakob Rueetschi]

Hello

I've just updated to Samba version 3.0.22 (previously v3.0.4a)
and get the following problem:

rpcclient enumdrivers fails with WERR_UNKNOWN_PRINTER_DRIVER
while rpcclient getdriver works just fine!  Can this be?

$ rpcclient -c enumdrivers GUTENBERG
Password: ********
result was WERR_UNKNOWN_PRINTER_DRIVER

$ rpcclient -c 'getdriver lg403-lj5000' GUTENBERG
Password: ********

The (presumably) same behaviour also shows in Windows:
I can install drivers into the print$ share from a windows
client and it works. But the list of available drivers on
the server remains empty.

Any ideas on what causes this behaviour?

Thanks a lot,
