[GENERAL] Any good HOWTOs on LDAP with PostgreSQL 8.1?

[vishal saberwal]

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?

thanks,
vish
