Confirmed fixed in 10.12.0-rc.2
Afaik we have two flavours of the webdav api:

1. (as advertised on the admin web UI) remote.php/dav/files/
2. (as used here) remote.php/webdav (with username taken from authorization)

Afaik, 1) is the new API, and 2 is the old API.
@T0mWz why do we advertise the 'old' API here? -- Or am I mistaken here?
