ldaps tests not working if port 389 not open?

[Epp, Matthew Mr CTR USA USA]

Is there an open issue where this is still occurring? I am trying to monitor ldap servers with only 
port 636 open, and although the port is open (confirmed via telnet) and ldapsearches from the 
command line work, bbtest-net fails to connect even if port 636 is specified as part of the URI.

I am monitoring other servers for ldaps where both port 389 and 636 are open, by the way.
