Hi,

After spending several hours of trial&error, reading documentation and 
googling around my last resort is to ask for help in this mail list.
I need to do proxy authentication, but as the CAS cannot directly access 
the application(s), I wanted to include the proxy granting ticket in the 
validation response as described here: 
https://apereo.github.io/cas/5.2.x/installation/Configuring-Proxy-Authentication.html

The endpoint called is /p3/serviceValidate

The service config is:
{
  "@class" : "org.apereo.cas.services.RegexRegisteredService",
  "serviceId" : "https://ckoewiki.dev.mydomain.com/bin/view";,
  "name" : "CKOE wiki",
  "id" : 2,
  "description" : "Only ckoe wiki auth with proxy",
  "evaluationOrder" : 2,
  "proxyPolicy" : {
    "@class" : 
"org.apereo.cas.services.RegexMatchingRegisteredServiceProxyPolicy",
    "pattern" : "^https?://.*"
  },
  "usernameAttributeProvider" : {
        "@class" : 
"org.apereo.cas.services.PrincipalAttributeRegisteredServiceUsernameProvider",
        "usernameAttribute" : "uid"
  },
  "attributeReleasePolicy" : {
    "@class" : 
"org.apereo.cas.services.ReturnAllowedAttributeReleasePolicy",
    "authorizedToReleaseProxyGrantingTicket" : true
  },
"publicKey" : {
    "@class" : "org.apereo.cas.services.RegisteredServicePublicKeyImpl",
    "location" : "file:/etc/cas/ubxnet.key",
    "algorithm" : "RSA"
  }

}



The response to the call I get is:
'cas:serviceResponse' => [
         {
           'cas:authenticationSuccess' => [
                {
                  'cas:attributes' => [
                    {
                      'cas:successfulAuthenticationHandlers' => [
                              'LdapAuthenticationHandler'
                            ],
                      'cas:authenticationMethod' => [
                          'LdapAuthenticationHandler'
                            ],
                      'cas:authenticationDate' => [
                            '2018-03-09T16:49:17.305Z[UTC]'
                          ],
                      'cas:isFromNewLogin' => [
                            'true'
                          ],
                      'cas:longTermAuthenticationRequestTokenUsed' => [
                                'false'
                              ],
                      'cas:credentialType' => [
                            'RememberMeUsernamePasswordCredential'
                          ]
                    }
                      ],
                  'cas:user' => [
                  'ckoe'
                    ]
                }
              ]
         }
       ]
    }

I had the assumption that maybe something with my encryption key is wrong 
(or what I put in the "location" parameter in the service config), but 
after investigation of the line 
2018-03-09 17:31:17,840 DEBUG 
[org.apereo.cas.authentication.support.DefaultCasProtocolAttributeEncoder] 
- <[proxyGrantingTicket] is not available as a cached model attribute to

I read 
https://github.com/apereo/cas/blob/master/core/cas-server-core-services-authentication/src/main/java/org/apereo/cas/authentication/support/DefaultCasProtocolAttributeEncoder.java
 


So I guess I miss an essential thing here. How can I get the PGT into the 
attribute cache? 
This: 
https://apereo.github.io/cas/5.2.x/installation/Configuration-Properties.html#clearpass
 
seems only to be necessary for the credentials... or am I wrong?

Any help is highly appreciated.

Thanks and regards,
Christian
