I have a Ubuntu 14.04 server running Moodle 3.1 I have installed all of the Office 365 plug-ins, and the Health Check passes fine.
When I log in, it authenticates the user, but doesn't seem to have any of the Azure AD information. The dialogue to edit the profile comes up to fill out first name , last name , etc..
Not sure if this is a an issue with Moodle 3.1, as I had an older test server that seemed to work fine. (Not sure which version of Moodle)
Thanks,
Rene
