What does Joomdle's Single Sign On (SSO) do?

Joomdle's SSO provides the following functions in response to user actions:

• When users are created in Joomla, they are automatically created in Moodle too.
• When the user is looged in Joomla or Moodle, he is automatically logged into the other one too
• When the user logs out of either Joomla or Moodle, he/she is automatically logged out of the other.

Why do I get the message "XML-RPC Error (7021): The transport method you are trying to use is not permitted"?

The transport method you are trying to use is not permitted is the error returned by Moodle to inform you that Moodle's XML-RPC is not recognising the configured IP address as a trusted host.

If you have configured Moodle's XML-RPC using 127.0.0.1, try using the actual servers IP address instead.

Why do I get a blank page when clicking on SSO links?

This usually happens when the Joomdle plugin is not installed/active in Joomla.

Why do I get the Moodle login page when clicking on SSO links?

This can be related to PHP sessions. Remember that www.site.com and site.com are different domains, so sessions are not preserved between them. You should always use the same domain, or redirect one to the other. For example, you may have configured http://mydomain.com to redirect to http://www.mydomain.com using the .htaccess file found in your root directory. An example of a redirection is below:

Rule for duplicate content removal : www.domain.com vs domain.com
RewriteCond %{HTTP_HOST} ^mydomain.com [NC]
RewriteRule (.*) http://www.mydomain.com/$1 [R=301,L,NC]
Check that the URL you entered in the Joomdle Configuration is the same as that in the RewriteRule.

I am using Joomla! 1.6 or Moodle 2.0, can I use Joomdle?

At this time Joomdle has only been tested on Joomla! 1.5. If you would like to install Joomdle and update the code to support Joomla! 1.6, we would welcome your contribution.

Moodle 2.0 is now supported.
