Field Detail

### __NO_USER

    public static Principal __NO_USER

### __NOBODY

    public static Principal __NOBODY

  Nobody user. The Nobody UserPrincipal is used to indicate a partial state of authentication. A request with a Nobody UserPrincipal will be allowed past all authentication constraints - but will not be considered an authenticated request. It can be used by Authenticators such as FormAuthenticator to allow access to logon and error pages within an authenticated URI tree.
