I used the following configuration parameters on LocalSettings.php but I still could read docs without logging in.
Me media wiki info:
dpkg -l mediawiki Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Installed/Config-f/Unpacked/Failed-cfg/Half-inst/t- aWait/T-pend |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description

ii mediawiki 1:1.10 website engine for collaborative work
What kind of docs? Uploaded stuff, or wiki pages?
Did you put that configuration at the bottom of LocalSettings.php?
V/r,
