IIRC, symlinks never take any other ownership or group or permissions.
Makes sense if you think in terms of security being provided by those
attributes of the target. Regardless of symlink settings, what would
happen if target attributes were changed and owner of symlink changed
its attributes? Who rules the roost? If you own the file, you may not
even know that someone created a symlink. You don't know the symlink
owner is spying/corrupting/spreading your data.

That assumes basic access control.
