We've AEM site hosted for public and authenticated users. Few sections of sites are only visible to authenticated users and we are controlling this through users and groups stored within AEM itself.
One of the requirement is to store users and groups in company shared user system. Due to security reason we cannot store any users in AEM.
If we externalize all our users/groups to an external system like LDAP or custom DB solution.
In this case how can I leverage AEM OOTB content authorization? what is the standard approach for public, authenticated users content authorization when users are stored outside from AEM?
