Administrator Plugin
--------------------
2002 Philippe Mingo <philippe@squirrelmail.org>

In order to use this plugin, you must first activate it using conf.pl and then 
you must change the config/config.php files permissions to 660. This file must 
be owned by the user who you want to have access to this plugin (only one user 
allowed) and the group must be the group of the user who is running php. This 
authentication method requires posix support in php and doesn't work, if user's 
id equals to 0.

An alternative method, but less secure, is to add a file called admins into the 
plugin folder with the names of the users that you want to allow the use of the 
plugin.

Use this plugin at your own risk, and always remember to make a backup of your 
config.php file before use.
