A method and system are directed towards enabling authentication in a distributed environment. The method employs a hashed salted password associated with a user in part to pre-authenticate the user. If the user is pre-authenticated, a ticket is transmitted to a client. The ticket includes a cryptographic digest of a concatenation of the local and remote addresses that is exclusive or'ed with a timestamp to generate a modified authenticator. The modified authenticator is directed at binding the timestamp to the client to minimize reuse of an authenticator. A packet that includes the authenticator is sent to a server. The server is configured to determine another remote and local IP address associated with the packet. Employing the remote and local addresses, the server extracts the timestamp from the modified authenticator. If the timestamp is within a pre-determined time window, the user may be authenticated.
A method for authenticating a client, comprising:
A system for authenticating a client over a network, comprising:
A computer-readable medium having stored thereon a data structure comprising data fields representing a ticket granting ticket that is issued to a computer for a user, including an authentication data field containing data representing a timestamp, a remote IP address, and a local IP address associated with the computer for the user.
An apparatus for authenticating a client, comprising:
