Re: Credentials Caching - Security Guy Not Happy

Good point, I suppose the client could send the username and mac
address of the computer to the server and server could combine the key
with the username so it changes per user per computer. Still may not be
that secure, but better than cleartext, some would say marginally but
at least it would stop the casual password thief. We would also pass a
security audit where they scan the disk for our passwords in cleartext,
although, I am not sure Security Guy would be sufficiently satisfied to
let us use it.
