Kerberos support in JDBC driver?

Hi,

Can anyone tell me if the Postgres JDBC driver supports Kerberos authentication?

I've looked around the websites + google, but all I can find is an old Changelog entry in a Redhat RPM:

http://rpmfind.net/linux/RPM/redhat/7.2/i386/postgresql-jdbc-7.1.3-2.i386.html

* Mon Aug 06 2001 Trond Eivind Glomsr?d <teg@redhat.com> 7.1.2-7
  - Enable kerberos authentication (#50644)
