IDM always changes LDAP port from 389 to 1389 when configuring through the UI.
Steps to reproduce:
1. Create provisioner json file for LDAP connection on port 389
2. Login to OpenIDM through the UI as openidm-admin
3. Open "Connectors" and click on the LDAP connector.
4. You can clearly see that the value is different, although different value is in the json file
