[Samba] Can't login from Windows PC to Samba using ADS?

[Michael Cesar]

Can somebody help expain to me what is going on in the winbindd log? I 
set the log level to 5 and ran the following from my pc:

net use *  \\10.0.10.29\web /USER:MBTMASTER\michael.cesar

This produced the following results (I omitted some lines because it 
didn't seem related):

MY OBSERVATIONS:
1) winbind retruned the correct user name to samba.
2) winbind (getpwnam) couldn't find the name michael.cesar in ??? Why?
3) winbind (getgrnam) tried to create a user with group of ()? Why? 
Where does it get this infomation?
4) winbind failed to authenticate because it could not find the group ().

Does anybody understand the inner workings of this? Thanks in advance.
