Please do not edit DefaultSettings.php. This configuration file includes, like the name say, default settings, so, if you update your MediaWiki version, this file will be override normally (and your changes are away). To define user rights and/or user groups, please use the LocalSettings.php and $wgGroupPermissions, like 88.130.94.75 explained. Additionally, you can use Manual:$wgRevokePermissions to revoke a permission for a special group (also, if this right is given by another group the user is a member of).
