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.
+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.
+you want to allow the use of the plugin. admins file must have
+empty line after administrator's username. If administrator name
+ends of end-of-file symbol instead of line feed, it will be
+ignored.
Use this plugin at your own risk, and always remember to make a
backup of your config.php file before use.
+
+Order of authentication checks
+------------------------------
+When plugin checks if user can use it, it first checks
+plugins/administrator/admins file. If file does not exist, plugin
+checks config/admins. If plugin can't find admins file, it tries to
+use uid based authentication.
