Hi Microsoft Team, We are facing an issue which is as follows: 1. We have a SQL based user management system. 2. Now, we are planning to getting AD enabled for our production. 3. The challenge is to see if for a desktop login, we can have the Active directory (AD) talk to the non-AD source like SQL for user authentication / authorization. We will need your help here in checking the technical feasibility of this. Please let me remind you that this is a non-cloud based infrastructure. Also, wanted to check if this is possible with a RADIUS configuration with AD (for desktop login).
