We have all of our child portals setup in a site group. We use a 3rd-Party authentication provider on the master site so that we can sign in with Azure AD.
Is it possible for me to setup the child portals in such a way that when a user attempts to login to the child portal, they are redirected to the master portal to sign in and then redirected back to the portal they are trying to login to?
That way the 3rd-Party authentication provider does not have to be setup on every single child portal.
For example here is what I want:
User navigates to child portal B.
User attempts to login.
User is sent to parent portal A where they sign in.
Once signed in the user is sent back to child portal B.
