Configure apache for multi-user-webdav

I have trouble enabling webdav for multiple clients (each getting access to their own area). I can only get them to share access to same area. If I enable the first part of the vhost-file you see attached .txt file, everything works 100%. However, that is just for one user. As soon as I disable the first part that is disabled attached, I can't login using WEBDAV. I'm using the following guide: [login to view URL] I just get the 405 method not allowed whatever I do. I have tried to play with apache-settings. I want you to set it up locally and give me the configuration. If we then do not solve it, remote help on my server. I'm using Centos 7.
