Interface User

All Superinterfaces:

Principal

All Known Implementing Classes:

FileRealmUser

public interface User
extends Principal

All users are principals ... perhaps in the native OS, perhaps not.

Users always have authentication information, which is used to validate a user's preferred credentials. Different kinds of realms use different kinds of authentication information. For example, realms could use X.509 public key certificates, shared passphrases, encrypted passwords, smart cards, or biometric data to figure out if the user's credentials are valid.

Users typically have attributes that identify privileges granted/possessed by the user.
