Carl,

Try these loggers to get details on the attributes and decision cas is making:

        <!-- DEBUG Found principal attributes [...] for [username]
                   Attribute policy [???] allows release of [...] for [username]
                   Final collection of attributes allowed are: [...] -->
        <AsyncLogger 
name="org.apereo.cas.services.AbstractRegisteredServiceAttributeReleasePolicy" 
level="warn"/>

        <!-- DEBUG Skipping access strategy policy - when no attributes rules 
are defined
                   These required attributes [...] are examined against [...] 
before service can proceed - when attrubutes are defined   -->
        <AsyncLogger 
name="org.apereo.cas.services.DefaultRegisteredServiceAccessStrategy" 
level="warn"/>
        <!-- DEBUG CAS will not authorize the release of ... given the service 
is denied access to all attributes -->
        <AsyncLogger 
name="org.apereo.cas.services.DenyAllAttributeReleasePolicy" level="warn"/>

You may need a more general logger, but try those first.

Hi,

I'm running the Internet2 Shibboleth IdP and delegating authentication to CAS 
v6.2 for authentication.  I know CAS can do its own SAML negotiation, but this 
is configuration my institution is currently happy with.

We are using the Unicon shibcas authenticator 3 
(https://github.com/Unicon/shib-cas-authn3) to make this work.

When the IdP passes authentication to CAS, I can have CAS service entries set 
up that can be used for displaying service info on our CAS login page just like 
a service using the CAS protocol.  However, the "accessStrategy" configuration 
doesn't seem to be working for this service.  Is this configuration not 
supported?  Authentication is successful despite the fact that the principal 
doesn't have the required attributes.

Here is my example service configuration:

{
    "@class": "org.apereo.cas.services.RegexRegisteredService",
    "serviceId": 
"https://account-d.docusign.com/organizations/7b69e84c-b873-4923-85b7-b9930c08d975/saml2";,
    "id": 6860,
    "attributeReleasePolicy": {
        "@class": "org.apereo.cas.services.ReturnAllowedAttributeReleasePolicy",

            "java.util.ArrayList",
            [
                "eduPersonEntitlement"
            ]
        ],
        "attributeFilter": {
            "@class":

            "completeMatch": false,

            "order": 0,
            "patterns": {

                "eduPersonEntitlement": 
"^https://docusign-sandbox.lafayette.edu/$";
            }
        }
    },
    "accessStrategy": {

        "unauthorizedRedirectUrl":

            "eduPersonEntitlement": [
                "java.util.HashSet",
                [
                    "https://docusign-sandbox.lafayette.edu/";
                ]
            ]
        }
    },
    "evaluationOrder": 6860,
    "name": "DocuSign Sandbox",
    "description": "DocuSign is an electronic signature and document routing 
service that securely transmits documents for signing.",
    "logo": "https://cdn.lafayette.edu/images/logos/docusign-100x100.png";,
    "properties": {
        "@class": "java.util.HashMap",
        "InformationURL": {
            "@class": 
"org.apereo.cas.services.DefaultRegisteredServiceProperty",
            "values": [
                "java.util.HashSet",
                [
                    "https://help.lafayette.edu/docusign";
                ]
            ]
        }
    }
}

Any help would be appreciated!
