Answer 1

symlinks are parsed by the ftp server and follow them only if there is access to this fs branch.
in this case, it is better to use mount -o bind in this case, the fs branch is supplied "directly", the program will not even know that it is in another place in the fs tree.

Answer 2

Symlink and distribute rights, or add a user to a group to services.
