This is login manager that you can specify in the security setup section of
configure. It instructs TWiki to
cooperate with your web server (typically Apache) to require authentication
information (username & password) from users. It requires that you configure
your web server to demand authentication for scripts named "login" and anything
ending in "auth". The latter should be symlinks to existing scripts; e.g.,
viewauth -> view, editauth -> edit, and so on.
See also TWikiUserAuthentication.
Subclass of TWiki::LoginManager; see that class for documentation of the
methods of this class.
this allows the login and logon cgi-scripts to use the same code.
all a logon does, is re-direct to viewauth, and apache then figures out
if it needs to challenge the user
