  • Patent number: 8074264
    Abstract: A server may bridge between a wide area network, such as the Internet, and a local area network and may process authentication requests from clients on the wide area network. The server may filter the requests to enable specific types of requests to pass, and may forward the requests to a credential server within the local area network and pass any responses back to the client. The server may be configured with some or all of a set of domain services objects, but such objects may be stored in a read only format. The server may further contain a minimum of or no sensitive data such that, if compromised, an attacker may gain little advantage. The client may request evidence of authentication available to devices within the local area network and may use the evidence of authentication to access services made available to the wide area network.
