We are developing an application which is internal application but must be accessible from Internet. We have used OpenID Connect to authenticate users. Users must have a valid account in our IAM platform (ISAM IBM Security Access Management) to be able to log in to the application. When users browse to the application they are redirected to our IAM platform logon page. Once they enter their credentials, they will be able to enter into the application.
Now we want to have some kind of authorization based on which AD group users belong to. How can we achieve it? After the user has been authenticated and redirected to the application does the application need to get information from AD? How?
