[Samba] samba Active directory and SSO

Dear all,

I guess there were a lot of posts about this subject, but Im really stuck 
& prefer start a new thread hoping that some of you 
won't mind re-posting to help the Samba NewBie that I am.

well, here is my situation:
- more than 1000 users on a hetegenous network, One Domain & the need to 
keep only one.

- I need my Linux Boxes' users to get authenticated against a single AD, 
therefore I installed Samba 3 on a redhat 9 kernel 2.4, 

- smbd, nmbd & Winbind are running

- the linux boxes joined my domain using the command
        [root@LinuxBox root]#net ads join -U Administrator%password 

- I am able to view the list of the users in the AC, with:
        [root@LinuxBox root]#/usrlocal/samba/bin/wbinfo -u 

HOWEVER, I get the listing in the format username  not the supposed 
MYDAMAINNAME+username

furthermore, when I try to logon the linuxbox using one of my AD users, I 
simply cannot
Please find below my config files: smb.conf, /pam.d./login & /etc/nsswitch

Thank you very much for reading my post & Please let me know if you need 
anymore information....

Best Regards,

smb.conf

Hi,

I think this must be set to no in order to show also the MYDOMAIN part,i.e
winbind use default domain = no

According to man 5 smb.conf you should set also winbind separator:

       winbind separator (G)
              This parameter allows an admin to define the character used
when
              listing a username of the form of DOMAIN \user.  This
parameter
              is  only  applicable  when using the pam_winbind.so and
nss_win-
              bind.so modules for UNIX services.

              Please note that setting this parameter  to  +  causes
problems
              with  group membership at least on glibc systems, as the
charac-
              ter + is used as a special character for NIS in /etc/group.

              Default: winbind separator = ?\?

              Example: winbind separator = +
