Examples of AuthenticationMethod

net.sf.jz3950.auth.AuthenticationMethod
ZAuthenticationMethod . ZAuthenticationMethod is an attempt to keep JZKit as flexible, yet as useful as possible to the widest possible audience. When we are creating a simple test client, we want to be able to create a Z3950 connection to an authenticated target using some hard-coded authentication parameters. However, the real world is much more complicated, and we probably need to take account new authentication systems such as Shibboleth and the UK athens system, as well as the possibility of using a local mapping of private user ids to z39.50 user/group/password authentication information. Different implementations of ZAuthentication method can do this for us. Ultimately, all (current) Z authentication schemes must resolve to none, anon, simple, or idpass structures, which need a number of parameters. These different realisations of ZAuthenticationMethod can do anything, from simply echoing static values for these values, to looking up in a remote database an appropriate type/user/group/pass for the userid given in the @version : $Id: AuthenticationMethod.java 5 2007-03-09 23:22:30Z gremid $ Copyright: Copyright (C) 1999-2002 Knowledge Integration Ltd. @author : Ian Ibbotson (ian.ibbotson@k-int.com)

Implement this interface to participate in the stackable authentication mechanism. See the AuthenticationManager class for details about configuring authentication handlers.
Each authentication method provides a way to map "credentials" supplied by the client into a DSpace e-person. "Authentication" is when the credentials are compared against some sort of registry or other test of authenticity.
The DSpace instance may configure many authentication methods, in a "stack". The same credentials are passed to each method in turn until one accepts them, so each method need only attempt to interpret and validate the credentials and fail gracefully if they are not appropriate for it. The next method in the stack is then called. @see AuthenticationManager @author Larry Stone @version $Revision: 4308 $
