Enabling WebDAV on OS X

I won’t re-write the article, but this weekend I wanted to turn on WebDAV on my Mac mini, and this article pretty much covered it for me. The article talks about using iCal, but do the steps and see the FAQ for additional tips on regular file sharing.
The only note I’d add is that Digest authentication didn’t work for me in OS X 10.4.10 — I had to use Basic authentication.
