Since a recent change that was applied by Microsoft, our Azure AD authentication module no longer works. Authentication requests that are sent to the Azure AD service return code 404 without an informative error message. This issue can not be fixed on our side but rather requires changes from the Microsoft side.
How does this affect you?
If you’ve configured and used the Microsoft Azure AD authentication module, you won’t be able to log in using it anymore. We’re very sorry for any inconvenience caused.
What actions have we taken?
We’ve reported this problem to Microsoft, but unfortunately, we can’t expect it to be resolved in the nearest future.
What can you do?
At the moment, we don’t have a workaround to allow you use your AD user accounts. We can recommend that you set up and use one of the other authentication modules.
