Anyone? Best way to authenticate postgres against active directory?

[Derrick <dstensrud@xxxxxxxxxxxx>]

I've been struggling with pam_ldap and a windows 2003 active directory 
server, trying to get postgres to authenticate against it.  I'm 
wondering what the best way to get postgres to authenticate against 
windows active directory would be?  I've posted the problem on the 
general mail list that I was having with pam_ldap but no response.  Any 
ideas, how to's, or good links would be much appreciated, and I'm under 
a time constraint.  Thanks a million in advance.
