samba - Jan 2009 - net getlocasid and getdomainsid not answering on BDC

Hello,

I have one PDC with a local master ldap backend and
one BDC with a local slave ldap backend.
I did not join the PDC nor the BDC to the domain
because I am not using winbind.

I have correct answers from the PDC:

pdc# net getlocalsid
SID for domain PDC is: S-1-5-21-XXX

pdc# net getdomainsid
SID for domain PDC is: S-1-5-21-XXX
SID for domain MYDOMAIN is: S-1-5-21-XXX

The BDC doesn't answer :

bdc# net getlocalsid
[2009/01/22 23:57:10, 0] utils/net.c:net_getlocalsid(497)
  Can't fetch domain SID for name: BDC

bdc# net getdomainsid
Could not fetch local SID

Is this expected ? Did I misconfigured something ?

This is with samba-3.0.22 and openldap-server-2.3.24.

Regards,
Thierry
