We are trying to implement a login which consists of a default client app as domain and multiple client id as sub-domain. Now when a user comes he authenticates the default client app and gets his access token.
Now using this access token and user information we have assigned him a sub-domain client id (tenant for our app). Is it possible to use access token from default app and current sub-domain client id combination to retrieve access token for sub-domain client id. We need a single sign-on experience. If not, is there any way to support single sign-on in this scenario.
