  1. POcas_devise single sign out doesn't work
    text
    copied!<p>Building a CAS client in rails 3.2, I use the gem <code>devise</code> with the extension <code>devise_cas</code>.</p> <p>Everything works fine login/logout.</p> <p>BUT When I try to logout directly on the cas server, using the <strong>single_sign_out</strong> system everything breaks and I have no idea how to solve my problem since it seems to me that it come from the gem I use...</p> <p>Here is what I get in my logs when the cas server try to inform me about the sign out:</p> <pre><code>started POST "/UserCasAuth/service" for XX.XX.XX.XX at 2013-07-23 15:08:47 +0000

href="https://github.com/nbudin/devise_cas_authenticatable/blob/master/lib/devise_cas_authenticatable/single_sign_out.rb" rel="nofollow">this file</a> at line 50.</p> <p>I believe none of the session managers are recognized. I have indeed removed ActiveRecord since i'm using mongoid, as mentioned in the <a href="http://mongoid.org/en/mongoid/docs/installation.html" rel="nofollow">installation doc</a>. So should I install another session manager or something? Devise can still its work without it (until the single-sign-out), so I believe it shouldn't be an issue?</p>
