Publish iCal calendars with local WebDAV server

To publish your iCal Calendar with the bundled OS X Apache web server, edit Apache’s configuration file in /etc/httpd. You must be root, so I expect you know vi and the workings of this file in general.

 % sudo vi /etc/httpd/htttpd.conf

In the Shared Library section, where modules are loaded, add these two lines in the same ordering in their repective sections:

LoadModule dav_module libexec/httpd/libdav.soAddModule mod_dav.c

Then somewhere in the global section add:

DAVLockDB /Library/WebServer/davlocks/DAVLockDB

I used this section to have a webdav folder managed by Apache:

<Directory "/Library/WebServer/Documents/dav">  DAV On  

  AuthName 'WebDAV'  

  AuthType Basic  

  AuthUserFile /etc/httpd/.htpasswd  

  AuthGroupFile /dev/null  

  <LimitExcept GET HEAD OPTIONS>  

    require valid-user  

  </LimitExcept>  

</Directory>

I want this folder protected (somewhat) by a password. To generate the password file
with MD5 passwords (not that old crypt!), please use the -m flag. The file is text. Note that http is vulnarable to sniffing attacks, so someone on your network can get at your password.

 % htpasswd -m -c /etc/httpd/.htpasswd user New password: not_safe  

 Re-type new password: not_safe  

 Adding password for user user

Then set up the folder with permissions.

 % cd /Library/WebServer/ % mkdir davlocks  

 % chown www:www davlocks  

 % cd Documents  

 % mkdir dav  

 % chown www:www dav

In iCal, choose Publish Calendar and specify http://localhost/dav/iCal. Do not FTP stuff into the dav folder; webdav uses its own locking, don’t confuse it.

Good Luck!
