Winbind and SSH

Hi, I am a bit of a linux newbie but I am trying to go over some systems that I have been left with. I have installed winbind, samba and ssh on a fresh debian server but I am having some problems give Active Directory users ssh access.

When I look in /etc/ssh/sshd_config I see that root and the user I created during install are added to AllowGroups line. Having a quick look around it seems to me that users should be added with AllowUsers, but when I try and change it I lose ssh access for root so I kept it as AllowGroups.

The previous admin set up a windows group, linuxusers, when I add this to sshd_config AllowGroups I am able to ssh to the server. When I then remove the group from sshd_config I am still able ssh to the server. I restart ssh with /etc/init.d/ssh reload. How do I remove access from users/groups?

I created a new windows group, websixssh, when I add to the AllowGroups in sshd_config users are not able to ssh to the server. Also if I add a new user to the old group, linuxusers, they cant ssh to the server.

The user gets a access is denied message, and in /var/log/auth.log
Jan 2 15:26:13 EUKWeb6 sshd[8090]: User masum.islam from euk-sb34110. not allowed because none of user's groups are listed in AllowGroups
Jan 2 15:26:13 EUKWeb6 sshd[8090]: Failed none for invalid user masum.islam from port 57116 ssh2

Does anyone have an idea what I am doing wrong?

Winbind can return the group and user details with wbinfo

The keyword is kerberos. Try googling "debian ssh activedirectory". These links all seem worthwhile, with the first one quite recent:
