postgres_fdw and Kerberos authentication

postgres_fdw is a great feature, but several organizations disallow to hold any kind of passwords as plain text.

Providing the superuser role is not either an option.

A nice way to meet security requirements would be to provide single sign on support for the postgres_fdw.

As long as you have defined a user in the source and destination databases, and configure the Kerberos authentication you should be able to use postgres_fdw.

I tried without success as follow:

jml@dcx1-005-jml =# CREATE SERVER "dcx1-006-jml" FOREIGN DATA WRAPPER postgres_fdw OPTIONS (host 'dcx1-006-jml', dbname 'ibis');

jml@dcx1-005-jml =# CREATE USER MAPPING FOR CURRENT_USER SERVER "dcx1-006-jml" OPTIONS (user 'jml');

jml@dcx1-005-jml =# IMPORT FOREIGN SCHEMA ibisl0 FROM SERVER "dcx1-006-jml" INTO "dcx1-006-jml";

ERROR:  could not connect to server "dcx1-006-jml"

DETAIL:  FATAL:  SSPI authentication failed for user "jml"

Am I doing something wrong or postgres_fdw does not support Kerberos authentication?

Is there any plan to support Kerberos authentication?
