Hi, 

I have been trying now for hours to get the SSO to work between our moodle site and mahara. Both are hosted on the same server within the same domain all at united hosting. 

For the first few hours I got the error about the site being unavailable but since reading posts here and on moodle.org and making some changes I now get the error. 

Unable to sign in via SSO.

We were unable to authenticate you at this time. Possible reasons might be:

* Your SSO session might have expired. Go back to the other application and click the link to sign into Mahara again.
* You may not be allowed to SSO to Mahara. Please check with your administrator if you think you should be allowed to.

I have followed all the guides to link the sites and I have reset the keys several times but nothing seems to work... HELP!

Many thanks

Matt

Hello Matthew,

Sorry you can't SSO easily from your Moodle to Mahara. Reading the forums on Mahara.org you certainly have noticed you are not the only who had got trouble in setting up this by the past.

But, as usual, it is very difficult to help you if the readers of this forum have no information about what is happening with your Mahoodle installation.

So, please provide more information about the version of Moodle you use and the documentation you have followed. And moreover provide the Apache and PHP error logs to know what happens when you try to SSO from Moodle. Without these it is difficult to give direction to investigate.

Regards,

Hi Dajan,

Thanks for your reply, our moodle version is 2.2.3 and I followed the documentation from mahara wiki site.

Hello Matthew,

Reading through the error log, there are a few things that you don't seem to have on your server or set up correctly.

• Do you have set up the config.php file for Mahara? It seems to be missing.
• You are also missing the gd extension on your server, but I don't think that this would impact Mahoodle greatly.
• Your Mahara database is not UTF-8.
• You seem to be missing another file: "PHP Warning: require(/home/moodle2p/init.php): failed to open stream: No such file or directory in /home/moodle2p/public_html/mahara/install.php on line 31"

Can you please check into solving the errors first and then try the setup of MNet again? Maybe a fresh install - if you haven't already used your Mahara site - might be best and set it up with the correct DB and set up the config file before you attempt to connect it to Moodle?

All the best.

Cheers

Kristina
