I’m looking to implement user authentication in my application. Here’s the scenario: the user management database resides on the client’s server, which could be either on-premises or in the cloud. Whenever a user logs in or creates an account, the information should be stored in the client’s database. Additionally, an authentication token needs to be generated. Azure Active Directory (AD) will then authenticate this token, and the response will be sent to our database, which is hosted on Azure.
And client get login successfully.
How can I implement this authentication flow effectively? Any guidance or best practices would be greatly appreciated.

I am trying to create Azure Ad and connect my application , but i am get stuck at some point and get confused so please help me out
