I've finally completed to update to the Referee namespace to restrict the read/write access to the Referee namespace to the specific Referees (and system adminstrators). I've done verification that the wiki is still up and in one piece, and verified the Lockdown extension is working.
There are warnings all over the Mediawiki site on the access-restriction extensions and documentation:
So while Lockdown extension will stop non-referees from viewing, or reading via other obvious access paths, pages in the Referee namespace there may be some hackish ways of reading the pages.
So don't post Real Life secret information (bank account numbers, passwords, answers to secret questions) in the wiki and assume they're safe.
There are warnings all over the Mediawiki site on the access-restriction extensions and documentation:
If you need per-page or partial page access restrictions, you are advised to install an appropriate content management package. MediaWiki was not written to provide per-page access restrictions, and almost all hacks or patches [or extensions] promising to add them will likely have flaws somewhere, which could lead to exposure of confidential data.
