Well, if SSL connections do work with MS Access, then the error must be
somewhere else.

How do you test the driver during developement? Are you using Access or a
handwritten program?

What I did was installing Postgres 8.2.4 _without_ the psqlODBC driver.
Afterwards I downloaded the latest MSI package [8.2.0400] from the psqlODBC
page and installed that version. Any chance that there are some
incompatibilites introduced by that?
