LDAP Authentication?

People,

After writing dblink-ldap (http://pgfoundry.org/projects/dblink-ldap),
several people have contacted me asking if this will give LDAP
authentication to PostgreSQL, because they need this. And this is before
I've even released it, so apparantly there are a lot of people who want
this.

You can do this today using PAM authenication, but this is not always
possible. Notably it's never possible on Windows, and there are several
unix platforms/distros that don't support it without a lot of work.

It should be fairly easy to write a LDAP "backend" to password
authentication using openldap, winldap or whatever ldap library is
available.

Before I start working on anything I'd like to check if a patch for this
would be accepted?
