I want to enable people to use LDAP to access their contacts from mail clients.
I would prefer if this information were not made public though... so I want to require authentication.
But Zimbra seems to use LDAP internally without authentication, and adding "require authc" to slapd.conf seems to stop mail sending etc from working
LDAP Security ? suggests blocking access to LDAP with the firewall but then people can't use it externally at all
Is there any way to configure openldap to do this or should I be filing something in bugzilla?
