smbldap-useradd and usrmgr.exe

I have got a Red Hat EL5 running Samba smbd version 3.0.33-3.7.el5
I have set it up as a Samba LDAP PDC for my domain MYDOMAIN
I setup a WinXP box and had it join the domain

I login in WinXP to the domain as the domain administrator

I want to use srvtools on the WinXP box (usrmgr.exe, srvmgr.exe) to add
users and machines to the domain.

On the smdb server I can add manage users and machines without a problem
using smbldap-tools.

However, when I try to add a new user to the domain using usrmgr.exe I get
the following error message :

    "A device attached to the system is not functioning"

On the server side, the smbd.log shows :

    ldapsam_create_user: Unable to allocate a new user id: bailing out!

Oddly enough I can delete existing users, modify their password etc. from
usrmgr.exe, so only adding users generate an error.

I look forward to reading your answers,
