samba - Mar 2005 - User bdupuis in passdb, but getpwnam(),fails! ...

Hi,
I have a PDC with samba Version 3.0.9-2.3-SUSE + OpenLDAP 2.2.15

When trying to join my Domain with administrator, it's working
When trying to join my Domain with another account I have this error in 
/var/log/samba/log/log.computername :
User xxx in passdb, but getpwnam(),fails! ...

Here is my getent passwd, Administrator is bind to root :
root:x:0:0:root:/root:/bin/bash
Administrator:x:998:512:Netbios Domain 
Administrator:/home/data1/samba/Administrator:/sbin/nologin
root:x:0:0:System User:/home/data1/samba/root:/sbin/nologin
InfoRD-1$:x:1007:515:Computer:/dev/null:/sbin/nologin
InfoRD-2$:x:1008:515:Computer:/dev/null:/sbin/nologin
bdupuis:x:1021:512:Benjamin DUPUIS:/home/data1/samba/bdupuis:/sbin/nologin
afreytag:x:1022:513:Arnaud FREYTAG:/home/data1/samba/afreytag:/sbin/nologin

For config they are on http://www.arzurproduction.fr/temp/ (with false 
passwd)

Thanks
