[Samba] "I have no name!" shown as username

[Guillermo Gutierrez]

Hello all,
I have setup my gentoo samba server as a domain member server of a
windows 2003 Active Directory Domain using winbind.

I am able to see all the users and groups with wbinfo -u and wbinfo -g
andwbinfo -t does not report any errors.
'Getent passwd' and 'getent group' return local and domain users and
groups.

My problem is that when I login as a domain user, my prompt changes to
'I have no name!@Solidus', with Solidus being my gentoo box.
In the /etc/pam.d/login and samba files I have specified it to use
system-auth-winbind instead of system-auth.

What could I be doing wrong?
Also I am able to get into the home directory from the network but not
my public share.

Here is a print out of my smb.conf:

[global]
        workgroup = MARKETSCAN
        realm = MARKETSCAN.COM
        server string = %h, Gentoo Samba Server %v
        interfaces = eth0, lo
        bind interfaces only = Yes
        security = ADS
        obey pam restrictions = Yes
        username map = /etc/samba/smbusers
        log level = 5
        log file = /var/log/samba/log.%m
        max log size = 50
        client signing = Yes
        os level = 2
        preferred master = No
        local master = No
        dns proxy = No
        wins server = 10.11.3.177
        ldap ssl = no
        socket address = 10.11.3.210
        idmap uid = 150000-550000
        idmap gid = 150000-550000
        template homedir = /home/MARKETSCAN/%U
        template shell = /bin/bash
        winbind enum users = Yes
        winbind enum groups = Yes

[public]
        comment = Public Volume on %h
        path = /home/samba/public
        valid users = @MARKETSCAN\ggutierrez, @MARKETSCAN\Administrator
        read only = No
        force create mode = 0766
        force directory mode = 0766

[homes]
        comment = Home Folder for %U
        valid users = %D\%S
        read only = No
        force create mode = 0700
        force directory mode = 0700
        browseable = No

Thanks in advance for any help.
