What do your LDAP logs show samba is sending as the queries?  In the past 
when I've had this problem it was related to my ldap suffix.  User queries 
worked, but group queries did not (I had groups in a seperate ou from 
users).  However, your user and group suffixes are not set in your 
smb.conf, so it's not the exact same problem I had.  Please send me the 
output from a:

net -d3 groupmap list
