Hello Mahoodle-professionals,

we are using Moodle 2.3.3+ and Mahara 1.6.5 working fine. But i´m not able to establish the mnet connection to SSO from Moodle to Mahara. Moodle uses a loadbalancer (mahara uses different subnet as moodle), according to the colleagues network permissions are granted.

All settings are done according to the current manual including an institution in mahara ("mahoodle")  with the XMLRPC-authentication. Public Keys on Moodle and Mahara are valid.

If a user clicks on the moodle front page the link to mahara in the box "Network Servers", forwarding to mahara works fine. But login doesn´t work. Frontend-error:

"

Sorry, we could not log you in.
 Sorry, we could not log you into Mahara at this time. Please try again shortly. If the problem persists, contact your administrator.

Going to the mahara machine and doing:
wget https://mdl-alpha.***.de/mnet/publickey.php
results in:

Retrying.

Any ideas? Further information to analyse i can give anytime.

Thank you!

kind regards
