Hi PJ. It may be possible already to connect to Sybase databases.
If you are using a linux or mac package, the connections for MS SQL use the FreeTDS driver, which is the driver you would need for Sybase.
So in your service config, you would just select MS SQL as the type of connection but put in all your Sybase connection info.
You may need to modify the file /etc/freetds/freetds.conf to reflect the correct version #. It is probably set to tds version = 8.0 for use with Microsoft. I would suggest trying version 5.0 for Sybase.
Please note that changing this setting will prevent you from using the driver to connect to MS SQL databases.
