We are running SCIM in Azure and are unable to create users where the primary email and userPrincipalName are not the same. In the documentation it says emailsoruserName but for users were the primary email and userPrincipalName are the same we have no issues.
Is the SCIM setup to not allow username and email to be different?
On a side note. While troubleshooting this I tried to do a GET to the /Users endpoint but no data was returned even though the request was 200 OK. Is that intended?
