[Samba] Samba 4 domain - Dead groups

[Bastian Machek]

Hi *,

I'm running a Samba 4 AD DC at home, which works pretty well, except one 
of my users has "dead" group entries, which cannot be mapped to a group 
name anymore. This is only for one user. As I'm having problems with 
idmap of that user, I assume the cause is these groups.

Is there any way I can get rid of those?

I tried samba-tool dbcheck and ADSI-Edit, with no luck what so ever.

Many thanks in advance,
Cheers,
Bastian
