[Samba] Update Samba PDC - win7 stop working

[Dr.Peer-Joachim Koch]

Hi,

we have tried to update our rather old samba PDC. The system is running
on Novell SLES 10  SP2 with the samba RPM from Sernet.
We stopped everything and updated (booting from DVD, using offline update)
the machine to SLES 11 SP1 started samba and everything was fine -
expect all WIN 7 and W2008XX Server.
Those clients were not able to use the domain.
XP and Vista (32 and 64) worked without any problems. After 2h of searching
we switched back to the old Installation, to get everything back to work.
The PDC is a virtual machine. so using the snapshot worked very well ;)

However I do not have the log files anymore :(

OLD
OS                                                Samba ver
SLES 10 SP2 (i586)                    samba3-3.3.4-39

NEW
OS                                                Samba ver
SLES 11 SP1 (i586)                    samba-3.4.3



*) Has anybody seen this kind of behavior ?
   (Doing samba update -> Win7 is not able to use the domain anymore)

*) Is there a way to test those steps ? The pdc is using our LDAP Server,
so we can not simply clone the pdc and test everything in a separate 
network...
(or we have to clone a couple of server ...)

*) When we update the PDC and we get everything working  - which version
is recommended (3.4.X // 3.5.X. // 3.6.X ) ?
