[Inf-IT DAVcl] infcloud in conjunction with baikal

Hello List, I have a functioning installation of baikal 0.9.1 on my Synology NAS. Now my concern is, to get infcloud working in conjunction with baikal. If it is possible to get help, I would be very grateful. The installation of baikal is in the root directory of web. Parallel to that infcloud is in the root of web. So I have two Installations parallel in web. There is an older article on this configuration at: https://thomastaucher.at/pages/infcloud-in-conjunction-with-baikal/. But I didn't get it working. Any ideas? Sincerely Martin
