sshd_config allowusers allowgroups

Hi there,

i want to setup more security for ssh server and just started playing around with the configuration file.
I added the definitions AllowUsers & AllowGroups to that file specifying a certain user and a group.
The tricky thing of it is, that i added a user to the configuration which is not member of the configured group:

AllowUsers abcd
AllowGroups admin

Now the problem is that the system doesn't allow login to the server with the error message:
User wxyz not allowed because not listed in AllowUsers --> but wxyz is member of admin group

Any idea? Is this normal behavior?

this works like this,
cat /etc/group
cat /etc/ssh/sshd_config
AllowUsers omair1 omair3
AllowGroups admin
in this case omair3 will only be allowed to login.
I hope you get the idea.

ok. thanks for the info. i understand now that both work together

Maybe you can help me with another issue:
I've setup key authentication for remote users which works fine.

Is there a way to send notifications to somebody who tries to login? I'm using the banner function - but this information is sent to everybody.

any idea? thanks in advance!
