Hi! I'm currently trying to install OpenLDAP in a 64-bit Ubuntu Server 10.04, and I trying to install it with PostgreSQL with UnixODBC (is iODBC better?) as its database. I tried several tutorials but they seem to give me errors like "Cannot contact LDAP server" or something.
The tutorials I tried so far:

I tried installing packaged PostgreSQL, and even an EnterpriseDB package... Stil, the problems prevail. I'm at a loss here... Can anyone suggest a working guide on this specific server setup?

Also, should I pre-install any package when I'm installing Ubuntu 10.04 Server? Maybe it affects my LDAP installations.

I was a Windows user my whole life and the whole concept of Linux was alien to me just recently.
