Authenticating a first user in a protected network to an application in a DMZ network shared simultaneously with a second user in an unprotected network. The first user supplies a userID and a password to a first server within the protected network for authentication for the application. The first server checks authentication of the first user based on the userID and password. If the first user is authentic, the first server forwards to the application an authentication key for the first user and a selection by the first user pertaining to the application. The application checks authentication of the key, and if authentic, complies with the selection by the first user. The second user supplies another userID and another password to the application. If the other userID and other password are authentic, the application complies with a selection made by the second user pertaining to the application.

System and method for authentication to an application

The present invention provides a computer-implemented method, system, and program product for managing log-in strikes in a geographically distributed computer infrastructure. Specifically, under the present invention, when a strike message is received on a strikeout server pursuant to an incorrect password input during an attempted log-in of a user, the incorrect password is compared to a strike list to determine if it was previously received on the strikeout server during a predetermined period of time. Based on this determination, the incorrect password and will be stored in a list on the strikeout server with a corresponding timestamp. Thereafter, the strike message and the timestamp will be replicated to all other strikeout servers in the infrastructure.
