Platform SSO for macOS not working

Intunestuff Oh sorry, i've immediately corrected this in my posting. I am surprised how I got this mixed up... Thank you for clarifying

Thanks, but the apple business manager is only responsible for synchronizing the devices to intune. The deployment itself is via Intune of course.
Maybe there are other ways i didn't know, yet?
Are you sure the "Token to User mapping" is necessary in this scenario? Do you have any documentation regardings this in context using ABM?

drumroll..... It works...

And the mistake was.... it was me... -.-

Although I said that I would check everything twice, I had a... blank space.... (right before the Extension Identifier value)

The pop-up appears immediately after this was fixed.

For the sake of troubleshooting i did not added the "token to user mapping", so i can clearly see what would have been the issue. Currently i'm testing the secure enclave mode and if it is working how it should work. I'm going to reply again when this is tested 🙂

(I've added a hint in the initial posting regarding the leading / trailing spaces in the configs and the URLs to be removed)
