Hi Brad,

Using the GSKit API for SSL (which is the recommended method, both
by IBM and by me) you do this by setting the GSK_CLIENT_AUTH_TYPE
attribute to the value of "GSK_CLIENT_AUTH_PASSTHRU" and then doing
the certificate validation yourself.   (I know this works, I've done it)

You can read about this here:

If you are using the SSL_xxx (yuck!) APIs, you should be able to
define an "exit program" (though, actually, it's a procedure not a
program) in the SSLHandleStr data structure.   Then, you do your own
certificate validation in that procedure.   (I haven't tried it, but
I read about it in the manuals)

You can read about this here (tho the docs are a bit thin):
