Hi all,

If I opened an LDAP port on our firewall for LDAP enquiry for our Mac clients, could anybody get our LDAP list through port scan from Internet? our staff got many fake spams recently in which the recipient addresses were exist on our Exchange Server. Does this problem related to I open the LDAP port to Internet?

I have disable the LDAP port now. Do I take any actions now?

Thanks
Thomas

Little late shutting the barn door, as the horse has fled. Yes a port query would have found the ldap port open.

What are they trying to log on to? You can limit the ldap queries to be only from the local network.
