Before I start playing with ncpmounts to my Vibe server, I thought I'd try WebDAV.
Netstorage on OES2 is working properly. I configured it for use with Vibe (R/W access), I can set up a mirrored folder as a user, but when I synchronize the folder, or when I attempt to add a file, it errors out with "405 Method Not Allowed" after a while.

Any ideas?
