[Samba] sysvolcheck on fresh samba 4.7 DCs

[mj]

Hi Andrew and Louis,

Found the issue: after rsync-ing the sysvol from our old decommissioned 
DCs, the sysvolreset/sysvolcheck DO work out.

I tried to keep the things simple first, by NOT immediately importing 
our old sysvol contents, but first check with a default sysvol...

I thought that the sysvolreset would just reset whatever is located 
under samba/sysvol, but I guess that it reads the directories from the 
database.

Once the on-disk directories matched the sam database contents, things 
worked fine.

Sorry... :-|
