It seems that Samba 2.2.8 is unable to open TDB files written by older versions. Instead it just overwrites them with a fresh file.
This caused our domain-server to loose the domain SID leaving all our NT clients out in the cold. We use a domain SID extracted from the previous PDC, an old WinNT 4.0 server that was scrapped.
Our print server also lost it's registry of printerdrivers and settings.
I have not seen any problem on the two Samba PDC's I upgraded (although my test
system went from 2.2.7a to 2.2.8 via 2.2.8pre2). I seem to be able to logon as a domain user and access network drives OK. Roaming profiles seem to
copy OK. I can use rpcclient to enumerate drivers OK, but I have not really been
using Samba for printing because of the printer settings problem on Solaris
(hopefully fixed now). I only have Windows 2000 clients.
It is probably worth posting more information about your setup.

Nick
