It's not a untrusted network. instance 1 and 3 are in a DMZ with
restricted access by firewalls several levels of firewalls. I don't know
the complete details of the architecture but i am confident in it (i
have no other choice).
For the moment, instance 3 can't accept modification except with the
bind DN of the updatedn parameter.
Which solution can i have ?
- setup 2 masters and 2 back-ldap that synchronize each one in a direction ?
- another solution
