postgres kerberos how to

[Derrick <dstensrud@xxxxxxxxxxxx>]

I was wondering if anyone out there could point me in the right 
direction.  I'm looking for a decent how to on using postgresql's built 
in kerberos support to authenticate against windows 2003 active 
directory.  I was trying to use pam_ldap, but had to give up and decide 
on using kerberos instead.  Any help what so ever is much appreciated.  
Thanks.
