thanks for the answer.
the truth is, iÂve alrady been through the test045 but canÂt understand
is going on there. the openldap admin guide seems to be a lot more verbose
about much simpler subjects and very sparse about something which does not
seem so straightforward (and used to be so simple in slurpd times).
my scenario seems pretty usual (like secured rw copy of DIT on lan, while
only copy on dmz - for mail server, apache auth, etc.)
in this very usual and IMHO wise setup the DMZtoLAN traffic is undesirable.
and yet there is no solid documentation in admin guide.
any pointers to documentation would be much appreciated.
