Alternative to MediaWiki which has permission for each post/article

Question

Is there any good replacement for MediaWiki (open source is preferable) with build in per-page access management? I know there're plenty of extension for wiki that could do that but my client doesn't feel totally comfortable about using these. This is a warning message from MediaWiki page that appear on SimpleSecurity extension's official homepage that scare my client when I propose the SimpleSecurity solution to him:

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 promising to add them will likely have flaws somewhere, which could lead to exposure of confidential data. We are not responsible for anything being leaked, leading to loss of funds or one's job.

DokuWiki has per-page read and edit permissions. Otherwise, DokuWiki has fewer features than MediaWiki. In particular, DokuWiki is problematic in changing page names or moving pages from one place to another. See this relatively complete comparison of the two.
