Hi, We still have a problem when ANONYMOUS_AUTH_FOR_CAS2 is enabled. When accessing a direct link ( https://nuxeo_server/nuxeo/nxdoc/default/5e84c7a3-e40c-4152-9497-b0cfdb916a6a/view_documents ) without being logged to the Nuxeo platform before, redirection is wrong https://cas_server/cas/login?service=https%3A%2F%2Fnuxeo_server%2Fnuxeo%2Fnxstartup.faces ( where service is the appURL parameter of the CAS2_AUTH authentication plugin ).

When ANONYMOUS_AUTH_FOR_CAS2 is disabled, redirection works fine ( https://cas_server/cas/login?service=https%3A%2F%2Fnuxeo_server%2Fnuxeo%2Fnxdoc%2Fdefault%2F5e84c7a3-e40c-4152-9497-b0cfdb916a6a%2F%2Fview_documents )
