With the firewalls (both at the linux host and at the windows host) enabled
I can login as AD\administrator user from the same windows host I cannot
ssh to as a normal 'domain user' . So the firewall does not seem the issue
at hand.

My iptables rules:

# iptables -L -n
Chain INPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0           state
RELATED,ESTABLISHED
ACCEPT     icmp --  0.0.0.0/0            0.0.0.0/0
ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0
ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp
dpt:22

REJECT     all  --  0.0.0.0/0            0.0.0.0/0           reject-with
icmp-host-prohibited

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

What logs exactly would you like to see?

ls -l /var/log/samba/log.winbindd*
-rw-r--r--. 1 root root 10854 Apr 19 21:49 /var/log/samba/log.winbindd
-rw-r--r--. 1 root root     0 Apr 19 15:02
/var/log/samba/log.winbindd-dc-connect
-rw-r--r--. 1 root root 28532 Apr 19 21:51 /var/log/samba/log.winbindd-idmap
-rw-r--r--. 1 root root   133 Apr 19 21:45
/var/log/samba/log.winbindd-locator

How can I get more debugging info from winbind?
