Hi Hannu,

your problem is due to manually saved "parentGUID"s on SAM objects. I 
think we used this technology some time ago as some sort of hack but in 
reality (as it is on Windows Server) they should be autogenerated as it 
is now.

So, please edit your database using "ldbedit" eg "ldbedit -H 
/usr/local/samba/private/sam.ldb" and look for "parentGUID" attributes. 
Delete all occourrences.

This should fix the problem.
