GPP Data Sources - SQL With Username & Password

Hi,

I have been attempting to configure a SQL ODBC data source via GPP and just keep failing. After a lot of searching it appears as though the SQL data source does not recognise having a username and password.

So, my question is: If I need to create a SQL ODBC data source via GPP which has to have a username and password attached, how can I do it? Is it even possible?

Thanks.

Pete.
