I would need your kind help. I have a DirectAdmin server here and would like to make WebDAV available securely to one user account. I have searched the DirectAdmin forums and the Interwebs, but most threads/instructions that I find are either horribly outdated or somehow unresolved and I, myself, have no experience with WebDAV besides using it from a client perspective.

Is there anybody here with a bit of experience to explain it to me or a link to a good and recent HowTo?
I am running DirectAdmin on a Linux/Debian 9 system...

Thank you so much in advance & kind regards
Amitz
