Unalbe to sign in via SSO

Hello mahara/moodle users,

We're having some difficulties with the moodle/mahara* connection.
We've set up the connection as described in the manuals. Roles are defined, etc..

Everthings 'working' until an user wants to SSO to mahara.
In moodle the user clicks on te link tot mahara. The page opens, but we get an error:

Unable to sign in via SSO:

* Your SSO session might have expired.
** You may not be allowed to SSO to Mahara.

This happens every time, with every user. Even with the Admin.
Does anyone have the same problem and maybe a solution?

This is the url from the networking/network servers block:
http://localhost/moodle21/auth/mnet/jump.php?hostid=3

This is the url created/linked by mahara:
http://localhost/mahara/auth/xmlrpc/land.php?token=5834dd6546f47c3e9e8fe2db4e03f7e099a25b0e&idp=http://localhost/moodle21&wantsurl=

I've tried different possible solutions, but nothing helped so far...

Greetz,

_{* Moodle 2.1 & Mahara 1.4}

Hi JW,

I'll skip the question of whether your servers have their time in sync since you're going localhost to localhost.

Could you check your web server's error log. If you're running OS X, I think that it's stored in /usr/local/apache2/logs/error_log but I may not be right.

Most SSO errors are reported in the error log.

I find this in the error_report:

Do you know this error?

I've not come across this error before. Looking at the code, I think that your Moodle is sending invalid SSO details back. It's a while since I've looked in any details at the mnet/xmlrpc authentication side of things and this could be an edge-case bug.

If you're in a position to add a bit of debugging, could you add:

log_debug($xml);

after line 127.

It looks like the $payload variable is not being set if the message is neither encrypted or signed. Why it isn't encrypted or signed is another matter though, and I'm hoping that a dump of the data returned by moodle ($xml) will give us a pointer.

The output from this should appear in your error log when you try and SSO again.
