I was able to write the code successfully. 1) How can i add 2 users who can connect only one at a time to the server and once they are done the other can connect. 2) Do i have to write the code at CLient or Server to verify the user.

That or don't accept incoming connections. When your first connection is closed, go back to listening for more connections again. 2) You should have the server challenge a connection (ask for username and pass), have the client send the information to answer the challenge and verify the user on the server. You can't trust anything that a client gives you and thus must do the verification there. Plus usually the server is the one with access to the list of authorized users and can look it up quickly. Hope that answers your questions.
