Manual:$wgWhitelistRead

Details
If a group of users is blocked from viewing the wiki by using the $wgGroupPermissions setting... ...you may still want them to be able to view certain key pages, in particular the login page! This setting holds an array of page names that all users are allowed to view, regardless of their group permissions.

A recommended minimum is as follows:


 * until 1.16.x


 * starting with 1.17.0


 * starting with 1.18.0

This allows everyone to view the home page and the login screen. You may also want to include other pages such as help/about/contact pages.

With Special:PasswordReset is always whitelisted just like Special:UserLogin and Special:ChangePassword.

Anonymous users can only view: Special:Userlogin
Anonymous users cannot read or edit any other page, but can still create accounts: To additionally block account creation by anonymous users, add the following line: With anonymous account creation disabled, sysops will need to create accounts for new users manually (or a LDAP extension is used for authentication)
