CAS-5.3.8 displays cas login page before rediecting to openid provider login screen

[john]

Hi , I upgraded Cas from 5.2.3 to 5.3.8 and when i try to use the url http://localhost:8080/cas/oauth2.0/authorize?response_type=code&client_id=<CLIENT_ID>&redirect_uri=http://localhost:8080/test, cas displays default login page(For a second) before redirecting to OpenId provider login screen. I have set autoredirect to true for openid in cas.properties.

Any idea how to redirect to openid login screen without displaying cas login page.

Thanks

The redirect is handled by a Javascript snippet: you can remove other elements on the screen to "blank" things out, or move the redirect call into something more immediate; maybe a meta-refresh tag.

Hi John,

FYI, the redirect logic is in here: https://github.com/apereo/cas/blob/v6.0.1/webapp/resources/templates/fragments/loginProviders.html#L90

Also if I am not mistaken, the 6.0.1 branch already have this bug fixed, you can see the following for reference:
- https://github.com/apereo/cas/commit/ff69f0160b6a17c966fa70b7866c4e2b41f54a13

- https://github.com/apereo/cas/blob/v6.0.1/webapp/resources/templates/casLoginView.html#L16

Cheers!

Hi John,

I recently did this exact thing for another business.  What I ended up doing was applying "display: none" to the main elements of the pages.  In the scenario that I just implemented, they wanted all views hidden except for the generic success and logout views. So I just implemented conditional CSS rules.

Keep us posted and good luck!
