My GoogleFu has failed me! I've seen issues similar to ours but no resolutions as yet that I've found, the answers I've found here are for similar questions but were older posts.
We are on Moodle 3.1.7 and have the OpenID Connect (and Office365) integration up on a test server. All users currently use LDAP for authentication, with SamAccountName being mapped to ID Number. We want to move all users to OpenID; I know we can install the Microsoft Block and have every user do it manually, and for ITS folks this was fine, but I'm not sure 4,000 less technical people can do it without a flood of calls to the helpdesk. Is there a tool or process to move everyone to OpenID in one shot?
