[ZendTo] MS LDAPs

[Scott Silva]

In my case I know the ports are open because I have a Linux based spam filter that is able to auth secured.

Reminder: LDAPS would normally use port 636 instead of ldap/389 to talk to the domain controller.  Don't forget to check things between your ZendTo server and the domain controller:
- the outgoing firewall config on the ZendTo server
- the firewall on the DC (is port 636 open?)
- routing
- any intermediate firewall rules

Quick test: open a command prompt (CMD on Windows, any shell on *nix).  This will try to "telnet" to that port.
C:\> telnet "ip of your DC" 636
If a blank screen appears then the port is open, and the test is successful.
If you receive a connecting... message or an error message then something is blocking that port.
