You can check the the retrieved response for the claims.
For example the following claim works for Azure AD: “http://schemas.microsoft.com/identity/claims/displayname” to get the full name of the user.
In the IdP configuration you have to go to the Provisioning tab and under Just in time provisioning, you can add claims.
After clicking on New, you can click on Search which will give you an overview of the configured claims. When there are no claims added, you can these manually.
Hope this helps.
