It happens with any UID/PWD combination and i'm using sqlod32w.dll - the
unicode-version of the ODBC-driver.
The server is running MaxDB 7.5.0.8 and the ODBC-driver is version
7.5.0.10. I can connect to any SAPDB 7.4 with the same driver - even
with the same ODBC-DSN.

I try to connect to a database with _UNICODE=yes and
DEFAULT_CODE=UNICODE. Both SAPDB 7.4 and the MaxDB 7.5.0.8 are running
under Linux.

That's true, but it may be, that's not even your fault, but some weird
behaviour of MaxDB 7.5.0.8 - so what further information do you need?

The ODBC-trace deesn't contain much information. I can see that the
Application tries to connect, and the error-message i mentioned above is
listed. Nothing more.
