Solved v18 - SSO Microsoft 365

[flamaltios]

Quick question. I upgraded v16 to v18 all OK.
I enabled the Microsoft 365 SSO, under the (previously existing) extensions it now says synced with 365 on the users that are available within 365, so far OK, my users get matched OK with the existing extensions. Except when people actually try using login with the Microsoft button, they get back to the same login screen.

I have an second (test) server with extensions that were all created via the "User Sync", these users are working OK with the Microsoft button.

Nick,

I saw you responded to my post before I deleted it in the other thread. You are quick .

"Are you sure you followed the instructions under Management Console --> Settings --> Microsoft 365, in the "Configure" tab?

Particularly:
5. In the app "Authentication" section, on "Implicit grant" enable "ID Tokens"."

I going to check.
EDIT: I was missing the ID tokens. I am sorry for my mistake.
