[Samba] problems w/samba-3.0.30 and NT4 PDC

[Chris Smith]

After upgrading to samba-3.0.30 on domain member servers using NT4 as 
PDC and running winbind users can no longer access the shares, they get 
prompted for passwords (which shouldn't happen) yet still cannot 
connect. Dropping back to 3.0.28a works (even after adding the recent 
security patch) fine.

What can I provide to get this fixed?

Thank you,
