The $wgWhitelistRead parameter works only partially for categories. When a non logged user goes to [[Category:xx]] page, he gets the 'you must login' message, BUT still sees articles/categories in the category. Not critical per se as he probably won't be able to access articles (if not in white list), but strange nontheless.

Both aspects work for me using SVN trunk. Reading of category pages is blocked completely when the user doesn't have read permission, and whitelisted categories can be read as normal. Resolving this fixed as of some time ago.
