[Samba] Trustdom not working if trusted smbd > 3.2.4

[François Legal]

I'm trying (for a while now) to upgrade to 3.3.x my samba PDC, but I've
troubles with the trusting PDC. 

While using samba > 3.2.4 on the trusted side, the trusting side can no
more enumerate users and groups from the trusted PDC. 

Winbind raises the error NETWORK_ACCESS_DENIED while trying to connect
with NTLMMSP. I saw this behaviour with 3.2.6, 3.3.0 and now 3.3.2 on the
trusted end. The trusting end work ok with 3.3.2. 

Can anybody help ? 

Thanks
