A method, system, and computer-readable code for delegating authority in a public key authentication environment from a client to a server machine or process, in order that the server machine or process can then securely access resources and securely perform tasks on behalf of the client. The authority is delegated by obtaining tickets (or other equivalent representation of user credentials) from a private key system, such as the Kerberos system, where the tickets identify a user's access rights or privileges. The present invention provides several alternative techniques with which this delegation model can be implemented. In these techniques, the client does not directly access the private key system.
