When I try to open a libreoffice document on a AFS directory that I have full write permissions to and that is not over quota, I always get this pop-up:
Document Could Not Be Locked
The lock file could not be created for exclusive access by LibreOffice, due to missing permission to create a lock file on that file location or lack of free disk space.
The lock file is created, but it has the size 0:
% ls -tla|head -n 5
insgesamt 32396
drwxr-xr-x 175 waschk sysprog 96256 Feb 5 15:11 .

I have just tested with the upstream packages of LibreOffice 6.4.0, the problem doesn't occur there, it creates the lock file on AFS with the right content (name, user name, etc.)
