public final class UNIXRealm
extends Realm
This class provides a simple implementation of a realm based on native UNIX (POSIX) notions of users and groups. When run on systems which don't support those notions, the UNIX realm will not be available. Also, note that many platform-specific features (such as shadow passwords and account creation/modification) are not currently accessible through this class.
