[Samba] Problem with samba + AD Win. 2003

[Nicolas QUINQUIS]

Hi,

Since 2 week, I try to join my Ubuntu server to an Domain Controller 2003
with krb, samba and winbind but even I try, I fail.

In fact, when I make a ticket with kerberos (kinit username at domain.lan),
it's a right but after, when I do :
net join administrateur at domain.lan, there is an error like :

[2011/07/08 15:16:02.638124,  0] libads/sasl.c:821(ads_sasl_spnego_bind)
       kinit succeeded but ads_sasl_spnego_krb5_bind failed: Invalid
credentials
Failed to join domain: failed to connect to AD: Invalid credentials
ADS join did not work, falling back to RPC...

Can you help me please?

Thx a lot,

Nicolas
