[Samba] Samba PDC Ldap integration

[Andy]

Hello all

I have set up a Debian etch server with a samba and ldap integration.

   domain master = yes
   domain logons = yes
   os level = 33
   preferred master = yes
   local master = yes
   passdb backend = ldapsam:ldap://localhost/

   ldap admin dn = cn=admin,dc=test,dc=net

   ldap suffix =dc=test,dc=net
   ldap user suffix = ou=users
   ldap machine suffix = ou=machines
   ldap group suffix = ou=groups

   ldap password sync = yes

I have added the machine into LDAP as a samba 3 machine.
I have added a user to the domain admins group.

When I try to connect a PC to the domain a error message pops up saying "the
following error occurred attempting to join the domain "test": The specific
network name is no longer available"

Would some know the cause of this?
