[Samba] cupsaddsmb question

[Mester]

Hi,

I had a working Samba PDC server (v3.2.5) with CUPS printer server and 
automatic Windows driver installation.
But I had to add Windows 7 clients to the server so I updated the Samba 
from Lenny-Backports to 3.4.7. Everything seems to be OK, but when I run 
cupsaddsmb it does not add the drivers to the server. Everything is fine 
but at the last step (rpcclient setdriver x y) it fails. The error is 
WERR_INVALID_PARAM
What should I do to make cupsaddsmb work again?
