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
