Approximately so.
A problem that people from an enterprise network have access to the
server. And there is Windows in their network. Recently the virus has
stolen passwords at one of managers, has entered on the one of servers
and has download the bad software.
I would like will restrict access in case of simple larceny of
passwords by viruses, but I am not able to do it standard manner.
Because from server side all managers come from one ip addresses. Also
I don't want to setup authorization through a public key. Since it
isn't compatible with ldap authorization on the server. And managers
can come on the server without entering any passwords.
All that I want is a mandatory presence of a public key and standard
authorization with request of the password which is stored on the
server.
