this is what I did of course, but I could not find it there
When you can't find something, Google is usually your friend: in this case, for example, searching for "login to edit site:mediawiki.org" turns up the manual entry for $wgWhitelistEdit as the first hit, which used to do what you want and which notes that this particular setting has, in newer MediaWiki versions, been superseded by $wgGroupPermissions, which also does what you want. :)
