Kerberos/GSSAPI Instructions

Hi,

I am trying find any instructions to configure the pg-odbc driver to
participate in the kerberoes/gssapi based authentication. I need to do
this in both Windows and Linux environments. Can somebody help me point
to some useful links?

I am also failing to understand, is PG server forces the client to
participate in gssapi based auth, or it is based upon client's request
that PG server participates in negotiation, if PG server is configured
with kerberos  auth details?

Thank you.

Ramesh..
