Hi, I'm setting up a 3rd party spam filter (offsite) and there is an option to sync the users via ldap.
They have given me there public ip address. with which I will open the relivant port and only allow this IP to use it.
What I don't know is what port I need to open and what I need to do on the windows 2008 AD to make an external sync work
the server is windows 2011 sbs
