I think this is what you want though. Fortress User Authentication software

In many companies, controlling and registering user logins in the network is a problem. Network OS support their own user control and authentication methods -- but many times the vulnerabilities are evident. In other cases, companies need some additional features that are unreachable through the standard solutions. Fortress User Authentication knows what users are logged in your network, elapsed session times, incorrect logins operations, etc. Additionally, you can allow or deny network resource access without make changes to user policies.
