I'm trying to lock down ssh access.  I use exim for a mail server so 
I have a bunch of accounts on my w2k box.  I don't want most to be 
able to use ssh.

So reading the man file for sshd_config I added to the following 
entry to sshd_config:

#wrs 20051231 restrict email only nt accounts from ssh
AllowGroups ssh_allow

I added a local group using administration / computer management

I imported into my /etc/group file:
ssh_allow:S-1-5-21-1801674531-688789844-1060284298-1007:1007:

Windows shows it as:
C:\Documents and Settings\Administrator>net localgroup

Aliases for \\BAREFOOT

-------------------------------------------------------------------------------
*Administrators           *Backup Operators         *Guests
*Power Users              *Replicator               *ssh_allow
*Test                     *Users
The command completed successfully.


Attempting to ssh into my pc:
Administrator AT barefoot ~
$ ssh -l administrator 127.0.0.1
administrator AT 127 DOT 0 DOT 0 DOT 1's password:
Permission denied, please try again.
administrator AT 127 DOT 0 DOT 0 DOT 1's password:

Commenting out AllowGroups ssh_allow and restarting sshd lets me log 
in just fine.

A clue would be welcome.  The install was updated after I ran into 
these problems at 14:30 Eastern today.

Thanks in advance,

Wes S
