I've started setting up a trial account with ESS to see if it's going to work for us. I'm trying to get it to connect to my LDAP server, but it's failing with: Error: Unable to connect to subdomain.mydomain.com:389
That address points to a public IP address on my firewall that I have setup for NAT to the LDAP server in my network. I've also tried the public IP address of that server as well. Both fail. I've also tried to use LDAPS to no avail.
Is it safe to assume that it's not even getting to the authentication part of the process (looking up the Bind DN, etc)?
I know the LDAP server is alive and listening. I use Softerra LDAP Admin tool and it connects fine (inside my network as a local server), but I'm not familiar enough with this to figure out why it's not connecting outside the network. I would have thought it would come down to issues on my firewall, but I'm quite certain I have those rules setup correctly.
Is there some tool of some kind that I can use outside my network to give me a more clear indication as to where the breakdown is happening?
