ubuntu server + samba +AD

Hi there,
The ubuntu file server was installed with no additional packages.
Then server was joined to Windows domain using:

apt-get install likewise-open
domainjoin-cli join example.com Administrator

domain users can login using SSH with no problem.

Samba was installed following :
https://help.ubuntu.com/10.04/serverguide/samba-fileserver.html

Result:
I cannot access the shared folder using any domain account.
here is smb.conf

[global]

        load printers = no
        name resolve order = host bcast
        passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
        obey pam restrictions = Yes
        map to guest = Bad User
        encrypt passwords = yes
        realm = TORONTO.local
        passwd program = /usr/bin/passwd %u
        dns proxy = No

        winbind enum users = Yes
        workgroup = TORONTO

        panic action = /usr/share/samba/panic-action %d
