ABSTRACT:
A method and apparatus for disabling password-less remote logins. In one embodiment, the method comprises receiving a remote login request at a first computing system from a user of a second computing system. Both of the first computing system and the second computing system mount home directories from a file sever. The request includes a public key associated with the user. An authorized key file associated with the user is located in the home directories. The authorized key file has zero length and owned by a root user of the file server. The method further comprises prompting the user of the second computing system for a password in response to the request.
