What, to you, is a "valid user"?
What identifying characteristics of a "valid user" can the user send to
you
What identifiying characteristics of a "valid user" can your FTP
authentication module check?

Look into the user-id and password-management functions available in
the standard API for your OS.

Look for alternate user-id and password-management functions available
to you in your operating environment (LDAP or AD, for instance)

Write your code to accept the userid and password that the user gives
your FTP server and validate that tuple against whatever source of
identifying characteristics your environment provides for.
