Lets put it this way, to connect to the domain member your users must
be known to the underlying OS.

The domain member I am typing this on, uses a smb.conf very similar to
yours and has been up for nearly 16 days. The only difference that I
can see between your setup and mine, is the PAM configuration.

Ok lets try it :)


So… here the awnser for your last questions

Did you create the libnss_win* links ?

yes i have add winbind in nsswitch.

Do you require your users to have home directories on the domain member?

yes but not on this member
