3. Installing WebDAV services

3.1. Ground Work

To compile the WebDAV service with LDAP authencation capability, we will need to have the LDAP library files installed on the machine. The LDAP library files will be used to compile the LDAP module for Apache. Best way to get the LDAP library files is to download the OpenLDAP sourcecode from http://www.openldap.org and compile it to produce the required library files. You may use any other LDAP like IPlanet as well, but I recommend an OpenSource solution.

$ su

# ./configure --disable-slapd

# make depend

# make

# make install

3.2. Pre-configuring Apache

mod_dav requires that you have Apache pre-configured so that it knows where where everything is. Change back to the directory where you have the source files:

# cd /tmp/download # gzip -d apache_1.x.x.tar.gz # tar -xvf apache_1.x.x.tar # cd apache_1.x.x # ./configure --prefix=/usr/local/apache

3.3. Configuring and Installing mod_dav

As mentioned above mod_dav will be statically linked with the Apache installation. Start by extracting mod_dav files:

# cd /tmp/download # gzip -d mod_dav-1.x.x.tar.gz # tar -xvf mod_dav-1.x.x.tar

Change to the NEW directory which was created during the extract:

# cd mod_dav-1.x.x

Now configure the mod_dav package for static linking to Apache:

# ./configure --with-apache= /tmp/download/apache_1.x.x

Compile and install the files:

# make

# make install

mod_dav will have been partially compiled and placed into the Apache tree during the make install step.

3.4. Installing and configuring mod_auth_ldap

Change back to the temp download directory, and extract the mod_auth_ldap files:

# cd /tmp/download # gzip -d mod _auth_ldap.tar.gz # tar -xvf mod_auth_ldap.tar

Now install the modauthldap files to the Apache source tree:

# cd apache_x.x.x # mv ../modauthldap ./src/modules/ldap

3.5. Installing and configuring mod_ssl

# cd /tmp/download # gzip -d mod_ssl-2.x.x.tar.gz # tar -xvf mod_ssl-2.x.tar # ./configure --with-apache=../apache_1.3.x.x

3.6. Configuring and Installing Apache

Finally we have reached the destination. But not yet.......

"The Journey is the Destination" (Jerry Garica of Grateful Dead)

Now we are ready to compile and install Apache with WebDAV and LDAP authentication for DAV.

Change back to the temp download directory:

# cd /tmp/download

Change to the Apache tree directory:

# cd apache-x.x.x

Now set the variable SSL_BASE to the OpenSSL lib files. On tcsh it will be as following:

# setenv SSL_BASE /tmp/download/openssl-0.9.x

This will the compiler where to find the SSL LIB files.

And now configure apache for the compilation with mod_dav, mod_auth_ldap, and mod_ssl:

# ./configure --prefix=/usr/local/apache \ --enable-module=ssl \ --activate-module=src/modules/ldap/mod_auth_ldap.c \ --activate-module=src/modules/dav/libdav.a \ --enable-shared=ssl [...you can add more options here...]

--enable-shared is an optional, it tells the configure to compile SSL as dynamic module. Depending on the services that you will be providing, you may or may not need dynamic compilation.

Now compile the Apache and install it into the appropriate place:

# make

Now create the SSL certification on the web server

# make certificate TYPE=custom

Follow through the instructions, and you will have a certificate in no time. Remember CommonName is your FQDN (Fully Qualified Domain Name) e.g. dav.yourcompany.com

For details on creating and managing the SSL certificates, please read the section titled "Creating and Managing SSL certificates".

Now install Apache into its own directory

# make install
