Teradata ODBC Teradata Driver Not enough information to log on - Python/SQL Assistant ODBC

Hi,
 
I'm geting "Not enough information to log on" error message when trying to connect using the Teradata Python module, pypyodbc or SQL Assistant ODBC.
Using Teradata Python:
session = udaExec.connect(method="odbc", system=***,username=***, password=***);
*** - hide the real values.
Using pypyodbc:
('DSN=***;UID=***;pwd=***;autocommit=True)
The strange thing is that I can connect through Excel using ODBC...
THe connection string there is:
('DSN=***;UID=***;pwd=;)
 
Any idea what Ielse  could try?
Thanks,
DDKing
