+$lang['Permissions_extra_explain'] = 'Permissions are based on a; PERMIT, ALLOW, DENY, PREVENT system. By default users and groups are set to DENY access to all operations, to do anything users or groups have to be granted ALLOW access. When conflicts exist, e.g. a user having ALLOW permissions to a function belongs to a group that is set to DENY such a function the user setting takes precidence, i.e. in this case the user would be ALLOWed access to this function. Similarly a user denied access to a function will be denied even if they belong to a group that grants them access. If a user belongs to two groups one of which grants an ALLOW while another is set to DENY the user will be denied access.';
