[Samba] Winbind + SSH + AIX - Connection to aixserver01 closed by remote host

[RobertoBouza at bayviewassetmanagement.com]

Hello everyone, I'm posting this one again I hope to get some kind of 
help. Doing further test telnet works fine authenticating users but not 
SSH.

I was able to get an AIX box configured with winbind, and it looks like 
everything is working as expected but ssh to the machine and I hope you 
can help me with this.

On the AIX server I'm able to issue wbinfo -u and -g with the right 
information and also I'm able to do a "su - <AD user>" without any 
problem. But when doing a remote SSH I just get this:

Client:

debug2: channel 0: send open
debug1: Requesting no-more-sessions at openssh.com
debug1: Entering interactive session.

debug3: channel 0: close_fds r 4 w 5 e 6 c -1

On the server aixserver01:

Dec  3 11:23:15 aixserver01 authpriv:debug sshd[467118]: debug1:

So, it looks like everything is working but why do I get a connection 
closed?

Thank you.
