I managed to fix this by stopping Samba, deleting /var/cache/samba/* and 
the /etc/samba/secrets.tdb and then starting Samba again.

Now my question is: if I add a linux group to Users, how would I delete 
this accounting group if I needed to in the future?
Users (S-1-5-32-545) -> accounting

This is what started the whole mess..
