   * don't have to convert |unicodeName| to the server-side name when 
   * communicating with a news server.  It's US-ASCII except for some 
   * 'stand-alone' Chinese news servers that use GB2312 for newsgroup names 
   * violating RFC 1036. For those servers, it's GB2312. However, it can be any
   * other single and multibyte encoding in principle. The encoding of this 
   * string is stored in |nsINntpIncomingServer| because that's a server-wide

   * @name Authentication methods
   * NNTP authentication is slightly wonky, due to edge cases that are not seen
   * in other protocols. Authentication is not necessary; if authentication is
   * used, it could be configured on a per-group basis or even require only a
   * username and not a password.
   * Since passwords could be per-group, it is necessary to refer to passwords
   * using the methods on this interface and not nsIMsgIncomingServer. Passwords
   * for the server as a whole are found via the root folder. If the server is
   * configured to use single sign-on (the default), asking any group for its
   * password will result in the server's password, otherwise, each group stores
   * its password individually.
   * Due to this setup, most of the password management functions on
   * nsIMsgIncomingServer do not correctly work. The only one that would affect
   * the passwords stored on folders correctly is forgetPassword; using any
   * other on a news server would result in inconsistent state.
   * Before requesting either the username or password for authentication, it is
   * first necessary to call getAuthenticationCredentials. If the method returns
   * true, then groupUsername and groupPassword are appropriately set up for
   * necessary authentication; if not, then authentication must be stopped.
  /// @{

   * Gets the authentication credentials, returning if the results are valid.
   * If mustPrompt is true, then the user will always be asked for the
   * credentials. Otherwise, if mayPrompt is true, then the user will be asked
   * for credentials if there are no saved credentials. If mayPrompt is false,
   * then no prompt will be shown, even if there are no saved credentials.
   * If this method returns true, then groupUsername and groupPassword will
   * contain non-empty results that could be used for authentication. If this
   * method returns false, then the values of groupUsername and groupPassword
   * will be cleared if they had previously been set. This could happen if
   * mustPrompt were true and the user decided to cancel the authentication
   * prompt.
   * Note that this method will be executed synchronously; if an async prompt
   * is wanted, it is the responsibility of the caller to manage it explicitly
   * with nsIMsgAsyncPrompter.

   * Force migration of credentials from older versions of this codebase.
   * This method is normally called during the creation of newsgroup folders,
   * and it should not be necessary to call this method. This method also
   * forcibly deletes the old credentials, so that passwords would not be
   * leaked.
   * It is expected that this method will be removed once it is decided that
   * supporting migration from old versions of Thunderbird and SeaMonkey should
   * not be supported.
