The Objective of this document is to setup a Apache based WebDAV server that can authenticate against a LDAP server. You will learn how to install, configure, run, maintain and fine-tune a Apache-based WebDAV server. This document will provide the basic groundwork for setting up a WebDAV server. It will also provide information on fine tuning and maintaining the server.
Note: If you encounter any problems installing Apache or any of the modules please feel free to contact me.

This document is not a HOWTO on setting up LDAP server. For setting up a LDAP server please visit http://www.linuxdoc.org/HOWTO/LDAP-HOWTO-1.html

WebDAV stands for Web enabled Distributed Authoring and Versioning. It provides a collaborative environment for users to edit/manage files on web-servers. Technically DAV is an extension to the http protocol.
Here is a brief description of the extensions provided by DAV:
Overwrite Protection:
Properties:
Name-space management:
Using WebDAV technology people throughout the world can be working on the same document. With the locking mechanism that DAV provides, the person who is editing the resource will lock it for editing. Others can read it but not modify it. When the person who is editing the document, is done editing, he/she will release the lock, and then others can modify the documents as well.
Authentication to gain access to resources is available in HTTP. This HOWTO discusses using LDAP for authentication. Permissions using groups and users in LDAP directory can be setup to control read/write access to various resources(documents) on the WebDAV server, so that you dont need to share passwords to work on the same documents
If you are worried about people trying to sniff your traffic, and gain access to confidential data, then worry not - you can always use HTTP with SSL ver3. This is the best encryption available. This documents details on how to implement WebDAV server which uses SSL encryption for transferring data.

The tools needed to achieve this objective are:
Apache Web Server
LDAP Module for Apache
WebDAV Module for Apache
LDAP lib file
NOTE: All of these packages are free and are available for download on the net.
We will compile all the above mentioned packages to produce binaries for the Web Server. The WebDAV and LDAP module will be compiled statically into Apache. Static compilation results in faster execution times. Apache was chosen, because it is the most versatile web server ever to exist. Market Shares for Top Web Servers shows that Apache has the largest web server market share.
Apache is also being used by:
This document assumes that you have the following already installed on your system.
gzip or gunzip - available from http://www.gnu.org
gcc and GNU make - available from http://www.gnu.org
The document also assumes there is a LDAP server installed elsewhere which will be used for the authentication.
