How to make LDAP requests (Port 389) over AnyConnect 3.1 on OSX 10.11.6?

Question

It's my understanding that OSX doesn't like to allow VPN port traffic on ports under 1000.
How can we get LDAP requests to work for us?

Error:

ldap client error { [Error: getaddrinfo ENOTFOUND server.domain.local server.domain.local:389]
  code: 'ENOTFOUND',
  errno: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'server.domain.local',
  host: 'server.domain.local',
  port: 389 }

* server name changed to protect the innocent

Any chance this is because OSX can't resolve the windows host name?

Answer 1

Resolve the server name to its IP and use that rather than the network name.
