Authenticating using cloud authentication
An authentication mechanism in a local area network may use a cloud authentication mechanism to allow or deny authentication requests. A user may gain access within a local area network by entering a cloud identification and password, which may be verified by a cloud authentication mechanism. If the authentication is successful from the cloud authentication mechanism, the user identification and password are stored locally for subsequent authentication requests. In some embodiments, the cloud password may be periodically flushed so that subsequent requests may be passed to the cloud authentication mechanism. The authentication mechanism may be used in both domain and workgroup local area networks, and may operate in parallel with other users who may have local area network or client credentials which may not be authenticated from the cloud.
