Suppose a user process has authenticated itself against domain's directory server via kerberos, and then attempts opens a network socket to my server application.
My server application has a white-list of users from the domain directory server.
How does my server app authenticate the user from the directory based on this socket opening attempt?
(To keep things simple - let's say my server is written in Java, and the directory server is Active Directory)
EDIT My question is about how the client asks for an authentication token.
