Question

You register a single-page application in Microsoft Entra ID and configure it to receive group membership claims in the ID token. Users who belong to a large number of groups report that the application fails to load, and you discover that Entra ID is issuing an overage claim instead of the full list of groups because the token exceeds the size limit. The application needs to make authorization decisions based only on the specific application roles you have defined, not on all of the user's security groups. What should you do to resolve this reliably for all users?

Accepted Answer

Change the group claims configuration to emit only groups assigned to the application, and configure app roles that are assigned to users and groups, then use role claims for authorization.

Answer

Increase the token size limit in the application's manifest by setting the optionalClaims property to accept larger tokens.

Answer

Configure the group claims to emit the sAMAccountName format instead of the group ObjectId to reduce token size.

Answer

Switch the application to request tokens using the implicit grant flow so the group overage claim is resolved automatically.
