How To: Setup WebDAV and Apache2 for Private iCal Publishing

Question

Notes:
This tutorial will not cover the installation of Apache2 or the required modules.
These paths apply to Ubuntu Server, but should work with many Linux distros.
There are other ways to configure your DAV directory. I have chosen to use a sub domain.
For simplicity, I am using Basic HTTP Auth. *THIS IS NOT SECURE!!!* Do not rely on Basic HTTP Auth for true security. For more details: http://httpd.apache.org/docs/2.0/mod/mod_dav.html#page-header
The following commands assume that you will be using sudo or logged in as root.
1. Enable mod_dav and moddavfs: *a2enmod dav_fs*
2. Create a directory for your DAV: *mkdir /var/www/dav*
3. Create a sub domain site: *vim /etc/apache2/sites-available/dav*
4. Enter the following:
NameVirtualHost *
<VirtualHost *>
DocumentRoot /var/www/dav
DirectoryIndex index.php index.html
ServerName dav.yourdomain.com
</VirtualHost>
DavLockDB /usr/local/apache2/var/DavLock
<Location />
Dav On
Order Deny,Allow
AuthType Basic
AuthName "DAV"
AuthUserFile /var/www/user.passwd
Require valid-user
</Location>
5. Create the user.passwd file:
*cd /var/www/*
*htpasswd -c user.passwd*
+Enter username and password when prompted+
6. Reload Apache's config: */etc/init.d/apache2 reload*
You can now publish your calendars to: dav.yourdomain.com.
Enjoy!

How do you set up a webdav?
Lion doesnt know webdav! No Versions... forget the webda(v).
How does look your config?
DNS is correct?
Check with:
hostinfo (IP)
hostinfo (dnsname)
nslookup (IP)
nslookup (dnsname)
Does the user/group exist? can you log in over an other protocoll? like afp?
More informations please...
