Abstract
A computer network has a subnetwork of computers including a server, a first authentication server, a firewall, and network interconnect. This subnetwork is connected through encrypted protocol handlers and over a potentially insecure channel to a second authentication server. Some authentication requests, especially for users not authenticated in the first authentication server's database and determined by the first authentication server to be authenticatable by the second authentication server, are passed from the server of the subnetwork through the encrypted protocol handlers and over the potentially insecure channel to the second authentication server.
Claims2
A method of authenticating a user and authorizing access to a computer network comprising:
- providing an administrator's computer subnetwork comprising a first server, a first firewall associated with the administrator's computer subnetwork, a first encrypted protocol handler, a first authorization server, and network interconnect;
- providing a remotely administered computer subnetwork comprising a second encrypted protocol handler, a second firewall associated with the remotely administered computer subnetwork, a second authorization server, and network interconnect;
- providing a channel connecting the first firewall to the second firewall;
- upon receiving a login attempt to the first server, determining that the login attempt is of type permitted to be authorized by the second authorization server;
- passing an authentication request through the first encrypted protocol handler, the first firewall, the second firewall, and the second encrypted protocol handler to the second authorization server;
- and
- passing password, challenge and response information between the second authorization server and the first server to authenticate the login attempt,
- wherein determining that the login attempt is of a type permitted to be authorized by the second authorization server comprises verifying that the user identification of the user is not authorized in a database of the first authorization server.

- and
- passing password, challenge and response information between the second authorization server and the first server to authenticate the login attempt,
- wherein determining that the login attempt is of a type permitted to be authorized by the second authorization comprises verifying that the user identification of the user is present in a database of externally authenticatable users of the first authorization server.
