[Samba] Problems after upgrade to 3.0.21

[Michael Keightley]

We have two sites, one has a Solaris 8 PDC running Samba v3.0.20.
The other has a SuSE 9.3 PDC running Samba v3.0.20b.
I upgraded them both to Samba v3.0.21, and had similar problems.  Profiles were
often not being saved and I was getting an INTERNAL ERROR in the Samba log when
a user logged in.
I eventually had to go back to the previous version of Samba.  
This is the error on our Solaris PDC:
