Ack. This is something we need to fix somehow. The problem is that
if you get rid of the top-level userfolder, there is nothing to
perform authentication/authorization and the site is effectively
inaccessible :(
I have come up with a fix for this that will appear in 1.11.0.
You will now be able to delete the top-level user folder in
order to replace it. Note, however, that during the time that
you have no top-level userfolder, the mgmt interface for the
top-level folder will be accessible *only* to the superuser.
The fix involves only two files in lib/python/OFS/:
Application.py and ObjectManager.py. I have attached
new versions of these files that you can drop into your
1.10.2 installation if you like. After replacing the
files, restart Zope and you should be able to replace
your top-level userfolder with a userdb or other
userfolder-like object.
Let me know if you have any problems!
