[Samba] Winbind AIX

[Luc Birs]

Hello,

I'm trying to use Winbind with Samba.

My system : AIX 5.1 level 05
Samba 3.0.2

I think those files are well-configured :
/usr/lib/security/methods.cfg
/etc/security/user
smb.conf

When a user try to connect to the samba server, the error 
NT_STATUS_CANT_ACCESS_DOMAIN_INFO appears !
wbinfo -u send all domain users
wbinfo-g send all domain groups

wbinfo --authenticate =
plaintext password authentication failed
error code was NT_STATUS_CANT_ACCESS_DOMAIN_INFO (0xc00000da)
error messsage was: NT_STATUS_CANT_ACCESS_DOMAIN_INFO
Could not authenticate user DOMAINE+USER%PASSWD with plaintext password
challenge/response password authentication failed
error code was NT_STATUS_CANT_ACCESS_DOMAIN_INFO (0xc00000da)
error messsage was: NT_STATUS_CANT_ACCESS_DOMAIN_INFO
Could not authenticate user DOMAINE+USER with challenge/response

Do you know how to solve this problem ?
Is it a PDC-side problem or Unix-side pb ?

Thanks
