AuthProvider

public class DefaultAuthProvider
extends Object
implements AuthProvider

Default AuthProvider implementation. It authenticates against the ofUser database table and supports plain text and digest authentication. Because each call to authenticate() makes a database connection, the results of authentication should be cached whenever possible.
