Class WsGrouperKerberosAuthentication

java.lang.Object

edu.internet2.middleware.grouper.ws.security.WsGrouperKerberosAuthentication

All Implemented Interfaces:

WsCustomAuthentication

public class WsGrouperKerberosAuthentication
extends java.lang.Object
implements WsCustomAuthentication

 basic kerberos authentication for grouper, settings are specified in grouper-ws.properties
 note: this can be used for rest and soap, though it is not a bastion of security:
  1. for soap, ws-security would be better since a ticket is passed instead of user/pass
  2. for rest, Im not sure there is another option
  3. the user/pass is transmitted in basic auth, so make sure SSL is on
  4. passing the user/pass is not how kerberos should work since kerberos passes tickets and not passes
  5. the user is authenticated to the kdc, but an ssl service is not invoked, which would be the next
  level of verification since it might be possible for the kdc to be spoofed to the grouper-ws
