Any good HOWTOs on LDAP with PostgreSQL 8.1?

Can anyone point me to a good HOW TO on LDAP with postgreSQL
8.0.x or 8.1?

Also, while searching online, i came across dblink-ldap.
Is this another ldap utility or is it something i could use
to connect/link to a ldap application?

If what you're trying to do is access LDAP data from inside the database
like a view or such, yes, dblink-ldap is what you should use.
