[Zope] LDAPUserFolder at Zope root

[Oscar Figueiredo]

Hello,

this might be trivial but I just can't find a way to do it.  How does one
replace the initial UserFolder at Zope root with a LDAPUSerFolder ?  

I tried the dummy way : delete the acl_users with an intent to instanciate a
LDAPUSerFolder afterwards but that locked me out in a way I could do nothing
but recreate a new Zope instance...  skip-authentication-checking in
etc/zope.conf didn't help...

Zope 2.7 debian testing package.
