WebDAV installation

[Emilius]

I am trying to get WebDAV working on my CWP. I have found some older guides but it is just not working for me.
I am using Afterlogic WebMail Pro for my email app and all I need DAV for is to sync my contacts and calendars with my Android phone using DAVx5.
DAV should be accessed from mydomain/mail/dav.php. That is where WebMail Pro store all the data.

My skills are somewhat limited and I really need step by step guide for this if possible. I really hope somebody can guide me to accomplish this.

Is there any new, up to date guide for WebDAV?
