Hello all,

I recently upgraded from Samba 3.5.6 (the version contained in Debian Stable) to Samba 3.6.5 (the version from Debian Backports) in an effort to closer track the current development to try and chase some long standing bugs out.

I think I've resolved one problem but introduced another. I'm getting the "WBC_ERR_DOMAIN_NOT_FOUND" when I try to perform a SID to UID lookup much like so:

city-liza-lnx:/var/log/samba# wbinfo -t
checking the trust secret for domain CBJ_NT via RPC calls succeeded
city-liza-lnx:/var/log/samba# wbinfo -n CBJ_NT+kevin_elliott
S-1-5-21-505306839-1977890393-20515302-14949 SID_USER (1)
city-liza-lnx:/var/log/samba# wbinfo -s S-1-5-21-505306839-1977890393-20515302-14949
CBJ_NT+kevin_elliott 1
city-liza-lnx:/var/log/samba# wbinfo -S S-1-5-21-505306839-1977890393-20515302-14949
failed to call wbcSidToUid: WBC_ERR_DOMAIN_NOT_FOUND
Could not convert sid S-1-5-21-505306839-1977890393-20515302-14949 to uid


This looks like it has all the markings of following bugreport:

https://bugzilla.samba.org/show_bug.cgi?id=8371#c5
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=652679



Before I follow this upstream can someone sanity check my configs for me? I understand that much has changed between 3.5 and 3.6 regarding the idmaping.
