interface nsIAuthInformation;

 * An interface allowing to prompt for a username and password. This interface
 * is usually acquired using getInterface on notification callbacks or similar.
 * It can be used to prompt users for authentication information, either
 * synchronously or asynchronously.

   * Requests a username and a password. Implementations will commonly show a
   * dialog with a username and password field, depending on flags also a
   * domain field.
   * @param aChannel
   *        The channel that requires authentication.
   * @param level
   *        One of the level constants from above. See there for descriptions
   *        of the levels.
   * @param authInfo
   *        Authentication information object. The implementation should fill in
   *        this object with the information entered by the user before
   *        returning.
   * @retval true
   *         Authentication can proceed using the values in the authInfo
   *         object.
   * @retval false
   *         Authentication should be cancelled, usually because the user did
   *         not provide username/password.
   * @note   Exceptions thrown from this function will be treated like a
   *         return value of false.

   * Asynchronously prompt the user for a username and password.
   * This has largely the same semantics as promptUsernameAndPassword(),
   * but must return immediately after calling and return the entered
   * data in a callback.
   * If the user closes the dialog using a cancel button or similar,
   * the callback's nsIAuthPromptCallback::onAuthCancelled method must be
   * called.
   * Calling nsICancelable::cancel on the returned object SHOULD close the
   * dialog and MUST call nsIAuthPromptCallback::onAuthCancelled on the provided
   * callback.
   * This implementation may:
   *  1) Coalesce identical prompts.  This means prompts that are guaranteed to
   *     want the same auth information from the user.  A single prompt will be
   *     shown; then the callbacks for all the coalesced prompts will be notified
   *     with the resulting auth information.
   *  2) Serialize prompts that are all in the same "context" (this might mean
   *     application-wide, for a given window, or something else depending on
   *     the user interface) so that the user is not deluged with prompts.
   * @throw
   *     This method may throw any exception when the prompt fails to queue e.g
   *     because of out-of-memory error. It must not throw when the prompt
   *     could already be potentially shown to the user. In that case information
   *     about the failure has to come through the callback. This way we
   *     prevent multiple dialogs shown to the user because consumer may fall
   *     back to synchronous prompt on synchronous failure of this method.
