Thanks for the information. Bummer. I really don't care about file  
since trashing files could easily be done as well with other network
file systems that only have optional/advisory locking. Also, users are
either in the console, or they are in the field, so they would never
access their home folder by means of both methods anyway, while outside
of their home folder they have read-only access, so they can't do  
harm there.

What would be what I was hoping for is that one could have a webDav  
with SSL protected basic authentication based on the regular passwd  
and then have worker thread spawned for each login, running under the
user ID of the logged in person, i.e. a suexec-ed dav thread for each
logged in user.

Looks like Apache isn't up to that task. Is anyone aware of some other
software that can export a file system over the dav protocol?
I found
but that's just about all the documentation on that, so it's not clear
to me what this can do, and how it works...

The lack of per-user threads seems to be a rather severe limitation of
creative uses of apache...
...there's e.g. this great software phpXplorer ( http:// ),
which would do a lot of what I'like to do, but since Apache can't  
spawn per
user instances, it makes it pretty much impossible to use this as an  
to user's real home directories.

The only software that does something like that right now is  
Usermin's File Manager
module, which works great as a web interface, but of course doesn't  
offer a
dav equivalent.
