title: Restful CAS client and Proxy Granting Tickets
body: <p>I have an application that uses a CAS server to authenticate.  I first use a REST call to generate a ticket generating ticket which is then validated successfully and a service ticket is generated.</p>
  
  <p>My next step is to pass this ticket to another webapp as a parameter in a web service call and let them login to the same CAS server with it.  Apparently this kind of behaviour is possible if I use proxy granting tickets instead of ticket granting tickets but I can't see any way to get a PGT through the REST client.</p>
  
  <p>Can anyone help with getting PGTs, or am I on a wild goose chase? </p>
