Title: Redirect Loop Pt. 2 Last modified: August 21, 2016 --- # Redirect Loop Pt. 2 * Resolved [gpspake](https://wordpress.org/support/users/gpspake/) * (@gpspake) * [11 years, 10 months ago](https://wordpress.org/support/topic/redirect-loop-pt-2/) * Opening new issue because I resolved [the other one](http://wordpress.org/support/topic/redirect-loop-45) too quickly. * Here’s what I did: Deactivated all plugins. Activated twenty fourteen theme Installed/Activated Cas Maestro Settings: CAS Version 2.0 Server hostname: auth. uthsc.edu (Getting response) Server path: /cas/ * When I go to `newsdevl.uthsc.edu/wp-admin` I’m taken to our CAS login page with the url `https://auth.uthsc.edu/cas/login?service=http%3A%2F%2Fnewsdevl.uthsc. edu%2Fwp-login.php%3Fredirect_to%3Dhttp%253A%252F%252Fnewsdevl.uthsc.edu%252Fwp- admin%252F` * If I log in here I’m authenticated (Which I can confirm by checking another service and seeing that I’m logged in) but I end up with a redirect loop. * When I go directly to `newsdevl.uthsc.edu/wp-login.php` I’m taken to `https:// auth.uthsc.edu/cas/login?service=http%3A%2F%2Fnewsdevl.uthsc.edu%2Fwp-login.php` * If I log in here, again – I’m authenticated and sent in to a redirect loop. * It shouldn’t matter but I’ve tried this in Firefox and Chrome on multiple computers and I’ve also tried in Private browsing. * Any suggestions about what might be causing this? * [https://wordpress.org/plugins/cas-maestro/](https://wordpress.org/plugins/cas-maestro/) * _[Moderator Note: [No bumping](http://codex.wordpress.org/Forum_Welcome#No_Bumping).

Sorry for hearing that you are running into troubles. Can you activate the CAS debug doing the following steps? 1. Edit your wp-config.php and add the following line: `define('CAS_MAESTRO_DEBUG_ON', true);` 2. This will generate a log in yoursite.com/wp-content/plugins/cas-maestro/debug. log when you try to login using CAS. 3. Please try to reproduce the bug and send me the log (link or a saved version) to [henrique@mowta.pt](https://wordpress.org/support/topic/redirect-loop-pt-2/henrique@mowta.pt?output_format=md) * PS: If you wanna contribute, please issue Pull Requests at our Github at [https://github.com/vaurdan/cas-maestro](https://github.com/vaurdan/cas-maestro) 🙂 Every help is really appreciated! * Thanks.

Sorry for the lack of detail. I’ve gotten sidetracked this week but I’m going to get back on this tomorrow or next week. I think this issue is most likely a result of another plugin or server config. I’ll post as soon as I know more. * Thread Starter [gpspake](https://wordpress.org/support/users/gpspake/) * (@gpspake) * [11 years, 9 months ago](https://wordpress.org/support/topic/redirect-loop-pt-2/#post-5108043) * Sent my log file via email. * Thread Starter [gpspake](https://wordpress.org/support/users/gpspake/) * (@gpspake) * [11 years, 9 months ago](https://wordpress.org/support/topic/redirect-loop-pt-2/#post-5108045) * Just an FYI, I deactivated all plugins and activated the 2014 theme. Same results. * Thread Starter [gpspake](https://wordpress.org/support/users/gpspake/) * (@gpspake) * [11 years, 9 months ago](https://wordpress.org/support/topic/redirect-loop-pt-2/#post-5108049) * This appears to be a server config or plugin conflict issue so I’m going to resolve it for the time being so it’s not just sitting here open. * I’m not really sure what the root cause might be so if you have any ideas based on that log, I’d love to hear. I’m pretty sure it’s related to a plugin – possibly a caching plugin but I can’t be sure until I kick things around some more. It could also be an htaccess rule or something – which are often modified by caching plugins. * I’m going to try to isolate this redirect problem and I’ll post if I discover why it’s happening. * [treydock](https://wordpress.org/support/users/treydock/) * (@treydock) * [11 years, 8 months ago](https://wordpress.org/support/topic/redirect-loop-pt-2/#post-5108089) * I just ran into this too. * Here’s some of the debug logs * ` A4BC .START phpCAS-1.3.2 ****************** [CAS.php:450] 1CE7 .START phpCAS- 1.3.2 ****************** [CAS.php:450] 1CE7 .=> phpCAS::forceAuthentication()[ cas-maestro.php:229] 1CE7 .| => CAS_Client::forceAuthentication() [CAS.php:1101] 1CE7 .| | => CAS_Client::isAuthenticated() [Client.php:1083] 1CE7 .| | | => CAS_Client:: _wasPreviouslyAuthenticated() [Client.php:1189] 1CE7 .| | | | user =

You may want to try deactivating your plugins and see if you can get it to work on its own. * I think the root cause has to do with cookies not being able to keep session data. * [treydock](https://wordpress.org/support/users/treydock/) * (@treydock) * [11 years, 8 months ago](https://wordpress.org/support/topic/redirect-loop-pt-2/#post-5108091) * gpspake, Thanks for the suggestion. The only plugin enabled is “WordPress MU Domain Mapping”. This is a fresh install of WordPress 4.0 with multsite enabled. If I disable “WordPress MU Domain Mapping” I still have the redirect problems. * You mention cookies, so I tried in Safari (only browser I hadn’t used yet) and I logged in just fine. I had the person I created this particular site for log in without issue. * Thanks, – Trey * Thread Starter [gpspake](https://wordpress.org/support/users/gpspake/) * (@gpspake) * [11 years, 8 months ago](https://wordpress.org/support/topic/redirect-loop-pt-2/#post-5108092) * Well, CAS is a tricky beast. * [jlee42](https://wordpress.org/support/users/jlee42/) * (@jlee42) * [11 years, 8 months ago](https://wordpress.org/support/topic/redirect-loop-pt-2/#post-5108093) * I had a similar issue here. The issue turned out to be the permissions on the sessions folder for PHP. * By looking at the `session.save_path` value in the output of `php_info()`, I figured out where that folder was and corrected the permissions. This was caused by me changing the group apache runs as from “apache” to “www”.
