[Samba] BUILTIN\Administrators - failed to call wbcSidToUid: WBC_ERR_DOMAIN_NOT_FOUND

[L.P.H. van Belle]

Hai, 

I had a quick look at this. ( in the mid of server upgrades ) .. 

You config looks ok. 
This looks also ok. 
> wbinfo --sid-to-uid=S-1-5-11
> 15549 

Mine shows, 
wbinfo --sid-to-uid=S-1-5-11
3000003

Normaly on a DC you should see 30000xx, but thats probely from the samba 3 upgrade. 

Did you give these groups uid/gids, or did you use some mappings somewhere for these groups? 
And after the upgrade, did you run net cache flush and restarted samba-ad-dc? 

It should not matter what the uid/gid are if the checks all work out. 

So we have to find first why this is not working for you.
wbinfo --sid-to-uid=S-1-5-32-544
3000000 <<< my output. 

Compaired to your setup with to mine. 

( this one is default set to 0 , you need minimal 2 in my opinion, i preffer 4) 
winbind expand groups = 4 

Beside that, almost the same, i use bind9_dlz you internal dns. 
But that should not matter. 

Start with the net cache flush and restart samba-ad-dc. 



Greetz, 

Louis
