Now I've got it basically working for the admin user, I'm trying to
extend it to meet my needs - namely being able to log in as two

in theory though. When I start a session using Putty it askes me to
"login as:". Is this referring to logging in as some other user
which exists on my system?

It's asking for what account you expect to access on the target
system.

OK, I want to log in as "adam" so I copied the authorized_keys file
so it is used by sshd when I reply "adam" to the "login as:" prompt.
However, the client returns: "server refused our key" even though both
the public and private keys are identical to the working "admin"
session. Am I doing something wrong?

Here's a chunk of the server log, first for a successful "admin" login:

....and for an unsuccessful "adam" login:

Thanks a lot,
