KB-2637: Samba messages about "Could not receive trustdoms"

Centrify DirectControl ,   Centrify DirectControl Plugins ,  

12 April,16 at 11:10 AM

Question:
 
There is a recurring error every 5 minutes in /var/log/samba/log.winbindd:
 
winbindd/winbindd_util.c:289(trustdom_recv) Could not receive trustdoms
 
There is no additional info on these messages - What do they mean?
 
Answer:
 
Samba scans for trusted domains in 3 places in the code:
 
1) The first scan asks a DC in its local domain to enumerate the trusts within the forest - this should succeed.
 
2) The second scan requires samba to contact a DC in the root of the local forest and ask about other forest trusts. This may fail if access to the root domain of the forest is blocked by a firewall.
 
3) If the second scan succeeds, then the third scan is a series of scans where samba attempts to contact a DC in the root of trusted forests to enumerate the domains they trust (transitive forest trusts). Some or all of these forests may be firewalled.
 
Check to see if a firewall is blocking any of these scenarios. 
 
Note that this is a level 1 log, so it will show up under normal conditions:
 
DEBUG(1, ("Could not receive trustdoms\n"));
 
There is an undocumented smb.conf parameter that tells samba to stop attempting trust lookups based on the NTLM domain name
 
winbind:ignore domains = NTLMDom1 NTLMDom2...
