Configuring access restrictions to your wiki

Also see Preventing_Access You can customise user restrictions by placing some
or all of the commands below into LocalSettings.php.

# Specify who can edit: true means only 
# logged in users may edit pages
$wgWhitelistEdit = true;

# Pages anonymous (not-logged-in) users 
# may see
$wgWhitelistRead = array ("Main Page", "Special:Userlogin", "Wikipedia:Help");

# Specify who may create new accounts: 
# 0 means no, 1 means yes
$wgWhitelistAccount = array ( 'user' => 0, 'sysop' => 1, 'developer' => 1 );

If new account creation is limited to sysops only, it must be performed by first logging in as a sysop user, and then visiting the Special:Userlogin page. (Note: that page doesn’t seem to appear anywhere as a link once you’re logged in. You actually have to manually enter the address http://<YOUR_WIKI_SERVER_ROOT_HERE> /index.php/Special:Userlogin into the address bar.)

sspence corrects: On our server, this is actually found at http://<YOUR_WIKI_SERVER_ROOT_HERE> /index.php?title=Special:Userlogin

This might be useful for cases where editing (or even read access) should be performed by only a select group. MediaWiki can be a useful group collaboration tool on small as well as large scales.

When creating the whitelist, don’t forget to add the stylesheet pages, for example „MediaWiki:Monobook.css“ and „MediaWiki:Monobook.js“. Also add „-“ for the default style.

$wgSysopUserBans    = false;     
 # Allow sysops to ban logged-in users
$wgSysopRangeBans   = false;      
# Allow sysops to ban IP ranges
