I meet the following problem with Samba 3.0.20 and OpenLdap 2.2.26 :

When I join a domain from a Windows XP pro workstation, I need to do it

The first time, I get the following message : "The user name could not
be found.". Although the correct entry (matching the workstation's
netbios name) is created under Ldap at that time (I checked it).

The second times, the workstation can join the domain.

Everything else works correctly.

Has anyone already met this issue ?
Any hint or answer will be wellcome.
