CAS Authentication with Moodle Not Working

Hi All.

I am new to Moodle support and I have a couple questions. I am trying to set up moodle to use CAS Authentication on the following version of Moodle (1.98) and I get the following error:

Warning: DOMDocument::loadXML() [function.DOMDocument-loadXML]: Start tag expected, '<' not found in Entity, line: 1 in /moodle-fs/lms/public_html/auth/cas/CAS/CAS/domxml-php4-to-php5.php on line 72

CAS Authentication failed!

You were not authenticated.

If the problem persists, you may contact the administrator of this site.

phpCAS 1.1.0 using server https://cas-dev.humboldt.edu:8443/cas/login/ (CAS 2)
 

I have gone through the documentation on the forums and I have tried several things suggested but havn't found a solution to the problem. Do I need to enable LDAP authentication as well or do I need to import all the users first?

Thank you for any help.

Hi, 

I had the same thing. In my case, the problem was in incorrect configuration of the CAS auth plugin. My CAS serwer was 

https://something.sth.pl/cas/login

What needed to be entered in CAS auth plugin conf is:

hostname: something.sth.pl 
base uri:  cas/

Note that I omitted 'https://' and '/login' parts. This is because they are added (apparently) by Moodle. 

In your case, I'd suggest using:

hostname = cas-dev.humboldt.edu:8443 
base uri= cas/

Thank you so much!!! That did the trick I had the base uri set to cas/login.

After setting it to cas/ it logged in fine.

The hostname didn't need the port added.

Thank you so much for the help, I have been messing with this for almost two weeks!

Yeah! I have found the errors.

When set the cas_host as 'cas.com' in moodle's cas config.You must make sure that brownser,client,server could analysis it. Or you can use IP instead
