I set default recursive permission with setfacl on the parent folder, which I want to be inerited when nextcloud create a new file.
For example:
---folder1
------1.1
getfacl on folder1:
# file: .
# owner: www-data
# group: tom
user::rwx
group::rwx
other::---
default:user::rwx
default:group::rwx
default:other::---
Now if I create a new file (named 1.1) via nextcloud in folder1, then this file’s group is www-data, while I want it to be Tom.
