DB2 II V8 FP10 on AIX 5.2

I am trying to have DB2 II connect to Teradata and in the process getting the following error (create wrapper, create server, create user mapping are all completed):

SET PASSTHRU PAPROD
DB20000I The SQL command completed successfully.

SELECT COUNT(*) FROM DBC.TABLES
SQL1822N Unexpected error code "303" received from data source "PAPROD".
Associated text and tokens are "CLI2: BADLOGON(303): Invalid logon string.".
SQLSTATE=560BD

SET PASSTHRU RESET
DB20000I The SQL command completed successfully.


I can do the same successfully through BTEQ utility though using the same username and password:

BTEQ -- Enter your DBC/SQL request or BTEQ command:
select count(*) from dbc.tables;

select count(*) from dbc.tables;

*** Query completed. One row found. One column returned.
*** Total elapsed time was 2 seconds.

Count(*)
-----------
8512

Any idea, what could be wrong?

Thanks. Paul

have you also tried - create nickname ...
see what is returns
must be with a connection string setting to terradata
finally take a db2 trace and see how this is supplied to target

I get the same error message when trying to create a nickname as well!
