Need to connect to GreenPlum Database in SAP BI 4.0

Hi ,

We Need to connect to GreenPlum Database in SAP BI 4.0,

i dont see any specific driver to set up a system dsn for this data source.

So can any one share your experience if you built a universe based on green plum db(UNX using IDT in 4.0)

or even in earlier versions of BO how to create a system dsn for greenplum db,

which driver we need to use.
