Enable WebDAV Per User Basis

WebDAV is for remote file Upload, manipulation, and editing Usage. WebDAV stands for Web Distributed Authoring and Versioning, which is an extension of HTTP that lets clients edit/view remote content on the web.

This tutorial will guide you on how you can enable WebDAV for your user accounts.

Hardness :Medium
Requirements (main) : php 7.1 and above and Apache webserver

Step 1 :

Download and install composer

curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer
chmod 755 /usr/local/bin/composer

Step 2 :

Install SabreDAV- WebDav php based

su -l username -s /bin/bash
cd /home/username/public_html
git clone https://github.com/sabre-io/dav.git
cd dav
/opt/alt/php-fpm71/usr/bin/php /usr/local/bin/composer install
or
"use your own php 7.1 bin path" /usr/local/bin/composer install
mkdir data

**replace "username" with you User account name.

you can use PHP switcher or PHP selector or php-fpm

Now create an index.php file in dav directory

nano index.php

and add this script in it and save:


you can edit it like below to change the desired directory :

$rootDirectory = new DAV\FS\Directory('/home/username/public_html');

Fix the permission :

chmod 755 /home/username/public_html/dav
chmod 644 /home/username/public_html/dav/index.php

Step 3 :

As root user now you need to enable the Apache WebDAV modules and it sub required modules :

mod_alias, 
mod_auth_digest, 
mod_authn_core, 
mod_authn_file,
mod_authz_core, 
mod_authz_user, 
mod_dav, 
mod_dav_fs,
mod_setenvif

got to /usr/local/apache/conf/httpd.conf and uncomment (remove the # from the first line of each required module) and uncomment (remove the # ) Include "conf/extra/httpd-dav.conf" file in httpd.conf

Next you also need to add the Directory directive to the domain/subdomain vhost which you want to activate webdav :

for ssl vhost :

   <Directory "/home/username/public_html/dav">
		AllowOverride All
		SSLRequireSSL
		Require all granted
   </Directory>

for non ssl vhost :

	<Directory "/home/username/public_html/dav">
		AllowOverride All
		Require all granted
	</Directory>

*** ensure you added this in main domain vhost i.e. usually under first one and in tag : <VirtualHost 1.1.1.1:443> </VirtualHost>

after changes restart httpd server :

systemctl restart httpd

Step 4 :

Adding authentication to webdav access

In user DAV domain dir /home/username/public_html/dav create .htaccess add this rules for digest auth and rewrite rule :

RewriteRule (.*) index.php [L]
AuthType Digest
AuthName "dav"
AuthDigestDomain /
AuthUserFile /home/username/.htpasswd
Require user username-dav
Satisfy All

**replace username with user account username
***replace username-dav with the dav user name you created with htdigest command below

And create .htpasswd in /home/username and add the digest auth, you need to use htdigest :

htdigest -c /home/username/.htpasswd dav admin

**replace username with user account username

enter the password when prompted.

eg :
admin:dav:595a268370390fe3e20cfffdd583d610

here :-
username-dav : admin
realm : dav
pass : 595a268370390fe3e20cfffdd583d610

Step 5 :

Accessing webdav via domain

go to https://www.yourdomain.tld/dav or http://www.yourdomain.tld/dav

or you can use command line or webdav client in this eg I'm using cadaver package cli :

cadaver https://www.yourdomain.tld/dav
