Use case
We have setup SSO and Provisioning integration with BitaBIZ on our Entra ID.
We have changed a users email on our Entra ID.
The users new email has been synced and updated on the user profile in BitaBIZ.
After change of email the user can no longer log in with Single sign-on to BitaBIZ.
How to resolve the issue
BitaBIZ uses the email address as unique identifier in connection with Single sign on.
If your users have different UPN (user principle name) and email address on your Entra ID, then you need to change "Unique user identifier (Name ID)" claim to user.email instead of user.principlename.
How to change "Unique user identifier (Name ID)"
Go to the BitaBIZ enterprise application on your Entra ID
Open the Single sign-on section.
Click "Edit" in the "Attributes & Claims" section
In the "Required Claim" section change "Unique User Identifier (Name ID)" to be "user.mail" instead of "user.principlename"
