The <AccessControl> element is the root of an XML-based access control policy that prevents access to a resource unless the user's session satisfies the policy. It's a simple, boolean-capable language provided as an example of how to implement an access control plugin.

        <Rule require="affiliation"></Rule>
            <Rule require="user"></Rule>
            <Rule require="authnContextClassRef">urn:oasis:names:tc:SAML:2.0:ac:classes:Password</Rule>
            <Rule require="authnContextClassRef">urn:oasis:names:tc:SAML:2.0:ac:classes:TimeSyncToken</Rule>

The example above would enforce a policy that allows only Ohio State faculty or students, other than a single blacklisted person, if they have authenticated with a password or a time-synchronized token.

If you are using the AccessControl element in an external file outside of shibboleth2.xml, you may have to add the "type" attribute shown below.

<AccessControl type="edu.internet2.middleware.shibboleth.sp.provider.XMLAccessControl">
