Oracle Database Gateway for DRDA - Version to [Release 11.2]

Using DG4DRDA it is possible for users to connect to an AS400 with an incorrect password in the database link statement.
An incorrect password would be expected to give the following error -

SQL> select user from dual@dg4drda ;

select user from dual@dg4drda
ERROR at line 1:
ORA-01017: invalid username/password; logon denied
[Oracle][ODBC DB2 Wire Protocol driver]User / Password invalid. {28000}
ORA-02063: preceding 2 lines from DG4DRDA

but a successful connection is made instead and results from the SQL statement returned.
