I don't think that module supports the SAML2 protocol in CAS. If memory serves me right, it only is functional for applications that go through the CAS protocol and possibly SAML1.

It works very well for most applications except for our Google Apps for Education site. Here are my observations: - If I authenticate with MFA to Gmail on a new browser session, I get a blank page - All subsequent requests for Gmail succeed - If I am a user that does not require MFA, then authenticating in a new browser session succeeds Observations using the web developer tool in Firefox: No MFA required - Google redirects to CAS with a SAMLRequest - I enter credentials and POST to CAS - CAS returns SAMLResponse and gets POSTed to Google at /acs MFA is required - After entering credentials, CAS goes back to login page with duo request - I MFA authenticate and POST to CAS - CAS issues a redirect to /acs on Google with the ticket id - Google is expecting a POSTed SAMLResponse so displays a blank page So, it seems like the SAMLResponse goes missing when the Duo Security dialog is injected into the flow. Has anyone else run into this issue? Is there a solution for avoiding the blank page? -- You are currently subscribed to cas-user@lists.jasig.org <mailto:cas-user@lists.jasig.org> as: mmoay...@unicon.net <mailto:mmoay...@unicon.net> To unsubscribe, change settings or access archives, see http://www.ja-sig.org/wiki/display/JSG/cas-user -- You are currently subscribed to cas-user@lists.jasig.org as: arch...@mail-archive.com To unsubscribe, change settings or access archives, see http://www.ja-sig.org/wiki/display/JSG/cas-user
