Mediawiki, blocking unauthorised reading...

We want to allow just 5 people to access our internal website and block all unauthorised viewing and account creations.

We tried editing the Localsettings.php file

# Anonymous users can't create pages

$wgGroupPermissions['*']['createpage'] = false;

# Only users with accounts four days old or older can create pages # Requires MW 1.6 or higher. $wgGroupPermissions['*' ]['createpage'] = false;

$wgGroupPermissions['user' ]['createpage'] = false;

$wgGroupPermissions['autoconfirmed']['createpage'] = true;

But the website crashed, as main page could not be accessed after that.

Please advice, how can we achieve unauthorosed reads?

regards

Anth :-)
