Trusted AD user who belongs to "valid users" can not access Samba Server on samba-3.6.5

Thu Jul 26 21:00:27 MDT 2012

I have posted log.smbd logs with log level = 10

from the log of log.smbd , the list of SIDs in the user test1's token as follows not include
Adomain\sag1's SID : sid:S-1-5-21-1122027669-4162194335-1793782112-1619

if use a Adomain user which belongs to  Adomain\sag1 to access samba server,  his token includes Adomain\sag1's SID : sid:S-1-5-21-1122027669-4162194335-1793782112-1619
