This how to will allow you to configure a Postfix mail server with virtual hosting. Virtual hosting means that you can add as many maildomains as you want and subsequentially as many mailboxes for these domains as you want. Here we we use an LDAP backend for both the MTA (Postfix) and POP3/IMAP server (Dovecot), and a web based management interface.

I have been running with a MySQL backend for virtual hosting for some time, but when I discovered Phamm and the added FTP feature I decided to switch to LDAP as backend for Postfix with virtual hosting. In view of the fact that the installation and configuration guide of Phamm is lacking some basic information it took me quite some time to put it all together and get it working. Piecing it all together was not simple so I would like to share how I configured it and got it all working toghether.

This document describes how to set up the Mandriva Directory Server (MDS) on Debian Etch. The resulting system provides a full-featured office server for small and medium companies - easy to administer via the web-based Mandriva Management Console (MMC).

This document is a step by step guide for configuring Ubuntu 7.10 as a Samba Domain Controller with an LDAP backend (OpenLDAP). The point is to configure a server that can be comparable, from a central authentication point of view, to a Windows Server 2003 Domain Controller. The end result will be a server with an LDAP directory for storing user, group, and computer accounts. A Windows XP Professional SP2 workstation will be able to join the domain once properly configured.

This document describes how to set up OpenLDAP on Fedora 7. OpenLDAP is a directory server based on the LDAP protocol, that same protocol MS Active Directory is based on. OpenLDAP is an open-source implementation of the Lightweight Directory Access Protocol.

This howto will show you how to store your users in LDAP and authenticate some of the services against it. It will not show how to install particular packages, as it is distribution/system dependant, instead it will focus on pure configuration of all componenets needed to have LDAP authentication/storage of users. The howto assumes that you are migrating from a regular passwd/shadow authentication, but it is also suitable for people who do it from scratch.
