Okay, so I found the "problem". First of all, I checked the CASCookiePath folder and the cookie was created correctly and all the necessary information was there. At this point, I knew it was just a display problem and I replaced the php part of the secured-by-cas/index.php by this :
<?php foreach (getallheaders() as $name => $value) { echo "$name: $value\n"; } ?> You can find more here : https://www.php.net/manual/en/function.getallheaders.php This time, everything was well displayed but with the header "Cas-" and not "CAS_" as it was written in the guide I follow. So TLDR : In the php part of the secured-by-cas/index.php just replace "CAS_" by "Cas-" and it will be good. I spent about ten hours on this stupid problem, I hope it will help someone else :) -- - Website: https://apereo.github.io/cas - Gitter Chatroom: https://gitter.im/apereo/cas - List Guidelines: https://goo.gl/1VRrw7 - Contributions: https://goo.gl/mh7qDG --- You received this message because you are subscribed to the Google Groups "CAS Community" group.
