It happened around the same time, so not sure if it was due to this, but I changed my primary email address in Azure, and since then, I am not able to access the backend of our Samanage interface.
If I log in now, it just takes me to the general user's interface, and doesn't show I have any tickets. In the Azure enterprise application area, it shows me as an administrator, and I set up a second administrator and it goes to the same generic user interface.
Under my role it shows me as a requester, so it logs me in without any issue.
I remember having to at some point import something for the association between Azure and Samanage Service Desk, but I am not finding what that was.
I see this under provisioning.
If I got to update credentials on that page and do test under administrator, it fails.
