[Samba] Cannot join domain with samba-3.6.4

[Alex Still]

Hello,

We've been using samba for a while, up to version 3.4.x, without issues.

We're having trouble joining an AD domain with 3.6.4

OS is Solaris 10 x64
Kerberos : MIT krb5 1.10.1
DC serveurs are running Windows 2008

The error message is :
./net ads join -U aranskis
Enter aranskis's password:
Failed to join domain: failed to lookup DC info for domain 'FOO.NET'
over rpc: Logon failure
ADS join did not work, falling back to RPC...
Unable to find a suitable server for domain FOO
Unable to find a suitable server for domain FOO

I have tried to run the same command with "-d 10", but it dumps core
before completing :

Anyway, it goes far enough before crashing so I can see that :
it finds the correct sitename
gets the correct DC list

Then it crashes here (only with -d 10) :
ads_try_connect: sending CLDAP request to 10.219.244.38 (realm: CIB.NET)
     &response->data.nt5_ex: .......
   [...........]

Any hints on the best way to try and figure out what is wrong when
trying to register in the AD ?

Cheers,
Alex
