[Samba] Access denied-message when joining domain

[Huyth Jenssen]

Hello list.

I have Samba working as a PDC, but when I try to join from a XP computer I
get the message: "Access denied". The message appears right after I change
the domain name in the XP network settings and the login window pops up.
My smb.conf is:

[global]
        workgroup = DOMAIN.NAME
        server string = %h server (Samba, Ubuntu)
        obey pam restrictions = Yes
        passdb backend = ldapsam:ldap://127.0.0.1
        passwd program = /usr/bin/passwd %u
        passwd chat = *Enter\snew\sUNIX\spassword:* %n\n
*Retype\snew\sUNIX\spassword:* %n\n *password\supdated\ssuccessfully* .
        syslog = 0
        log file = /var/log/samba/log.%m
        max log size = 1000
        logon script = logon.bat
        logon path = \\%N\profiles
        logon drive = H:
        logon home = \\%N\%U\data
        domain logons = Yes
        dns proxy = No
        wins support = Yes
        ldap admin dn = cn=admin,dc=domain,dc=name
        ldap group suffix = ou=groups
        ldap machine suffix = ou=machines
        ldap passwd sync = Yes
        ldap suffix = dc=domain,dc=name
        ldap user suffix = ou=users
        panic action = /usr/share/samba/panic-action %d
        invalid users = root

[homes]
        comment = Home Directories
        path = /home/%S/data
        valid users = %S
        read only = No
        create mask = 0600
        directory mask = 0700
        browseable = No

[netlogon]
        comment = Network Logon Service
        path = /data/samba/netlogon
        write list = @admins
        guest ok = Yes
        share modes = No

[profiles]
        comment = Users profiles
        path = /home/%U/profiles
        read only = No
        create mask = 0600
        directory mask = 0700
        browseable = No

[printers]
        comment = All Printers
        path = /var/spool/samba
        create mask = 0700
        printable = Yes
        browseable = No

[print$]
        comment = Printer Drivers
        path = /var/lib/samba/printers



Also, I'm not quite sure if I need a domain. All I want to do is to create
different users with different rights, the data stored will be the same for
everybody, just different rights. Two printers will be shared and I want
everybody to have access to them.  I also want the users to be able to log
in from any computer in the network. Do I need a domain or can this be
solved in another way?

Thankful for any responses.
