When create registration is enabled, however, I am unable to create a new FA user. I receive an error "The user was not given a unique identification. This account cannot be used to login; thus, this login request cannot be completed."

According to the event log

How can I get the one-of-a-kind ID? When I open the bearer token in jwt.io, I can see my AAD OID.

"name": "Simon Roberts",
"oid": "fa87b189-7080-4050-aa1b-e77e113e6799",

"openid" is the name of my scope.

What am I overlooking?

It looks like the sub claim returned is not a UUID: 3XXJmjO2q9DQCmGWV8-dyv_EzpOT-m_IAc3NX5nuYXA.

FusionAuth requires all user ids to be a UUID.

The default unique identifier for OIDC is sub, but that can be changed under the Options tab.

So I'd try changing that to oid and see if you can create a user.

Thanks for using FusionAuth!
