public interface PasswdAuthenticationProvider {
  /**
   * The Authenticate method is called by the HiveServer2 authentication layer
   * to authenticate users for their requests.
   * If a user is to be granted, return nothing/throw nothing.
   * When a user is to be disallowed, throw an appropriate {@link AuthenticationException}.
   *
   * For an example implementation, see {@link LdapAuthenticationProviderImpl}.
   *
   * @param user - The username received over the connection request
   * @param password - The password received over the connection request
   * @throws AuthenticationException - When a user is found to be
   * invalid by the implementation
   */
  void Authenticate(String user, String password) throws AuthenticationException;
