Frediano,
So I did check the sources and it looks like under non-Windows
platforms the driver doesn't support
asking for the login information.

So I changed my code a bit passing SQL_DRIVER_NOPROMPT to SQLDriverConnect.

However, I still can't connect.

So I turned on the logging on freeTDS.

Attached please find 2 freeTDS log files:
- one is from the isql unixODBC session which is successful
- other is from my software which uses SQLDriverConnect which fails.

Both are produced with TDSDUMP environment variable.
By looking at those logs it looks like I have to retrieve the
userid/password pair and supply it
to the connection string.
But I thought that this is the job of the driver. Was I wrong?

If you need any more information let me know.

I am trying to connect to Sybase 16 server using freeTDS 1.00.14 and
unixODBC 2.3.5.

Thank you.
