Thanks for verifying Pete that it's not just us. This is a bummer. So Server Admin is off-limits for us for now. What seems bizarre is that Apple uses all these case-fancy paths -- /Library/ WebServer, /Users/Sites, but then creates an admin tool that disrespects case. Very annoying.


For us, this came up when installing Lyceum (the multi-user fork of WordPress), and creating an alias from /blogs (virtual) to / Library/WebServer/Documents/wwwrooot/include/lyceum/src. Lyceum would then look in some subdirectory of that location for its own data, e.g. /blogs/username would be mapped by Lyceum to include/ lyceum/src/wp-content/blogs/3 . And from there, it would try to pull up index.php -- which is where things probably connect to the Directory override stuff you mention below.

Anyway, long story short is that this bug breaks applications.

What you fail to realize is that Apple's default volume format is case-insensitivity. I believe there is a warning about formatting your volumes using case-sensitivity in one of the docs and only to use it for the sake of legacy compatibility or some-such. Anyway, on a case-insensitive volume, this is all a non-issue and Apple's apps are working as they intended.

In this case (no pun intended), the problem is not a case-sensitive volume. In fact it is irrelevant whether the volume is case-sensitive or not. The problem is the inconsistency in which case sensitivity is applied. HFS in its default configuration may be case-insensitive, but it is case preserving. And Apache IS case sensitive. Now there is the hfs_apple_module, but according to the limited docs available (kbase 107310 is all i could find), it implies that insensitivity applies only to security realms. Now if it is intended to provide other case-insensitivity to Apache it is not documented, and doesn't really work either.


Has anyone seen any further documentation on what services/features hfs_apple_module is supposed to provide? (beyond this article, of course)

As the OP and I have suggested, if you create aliases that contain capital letters in Server Admin, it will get folded to lowercase, and that doesn't work completely when doing directory based modifications. In the end, the problem lies with the Server Admin application. You can, of course, roll the config files by hand (which is what I do), but once you do that, you can't touch the web section of Server Admin again, or risk the possibility of your precious multi- cased aliases getting changed.

And remember that not all of Apple's supported file systems are case- insensitive (as I mentioned before, Xsan is case-sensitive). But like I said, the sensitivity of the file system isn't the issue here.
