I just got a coredump when enabeling LDAP_ALLOW_NULL_SEARCH_BASE in
backend.c and
doing a search on a null base (if somebody wants the corefile, I'll mail
it to you):

./ldapsearch -h localhost -p 400 -D 'cn=......' -w xxxxx -s one -b ''
'objectclass=*'
with '-s base' I get 'no such object'
and without '-s' I get everything.

I have one element with a null base (one from netscape btw), and using
the netscape LDAP
(the one I'm trying to replace) I can retrieve the element using '-s
base':

objectclass: top
objectclass: passwordPolicy
