[Samba] GPO problems on a 4.1.6 AD, classicupgraded, uncaught exception

[mourik jan heupink - merit]

Wow Marc, you're quick. :-)

Thanks for your reassuring words.

I created a backup and ran samba-tool ntacl sysvolreset, and that solved 
the issue. :-)

Strange that such a recent installation (4.1.6) needs a sysvolreset...

Anyway, thanks for your QUICK help. :-)
