I have a few seperate users on my server, one user for which I want to

dissallow ssh login. Now I've read the man page for sshd and I've read a lot

of the documentation on this, but I'm still not clear one one point. By

default, /etc/ssh/sshd.config shows all entries are commented out. I want to

add something like this:
AllowUsers user1, user2, user3
I added that in but also with an # in front like all the other entries. Now

I find that I can still ssh to the box with a user acct that I didn't

include in the entry. Should it be in there without the #? And if so, do I

also then have to uncomment all the other entries??
Thanks
