I would suggest 
find . -uid 500 -exec chown -h owner \;
find . -gid 500 -exec chgrp -h group \;

The -h option says do the chown or chgrp to the symbolic link
instead of following the symbolic link.  Without the -h option,
the symbolic link is followed, causing the symbolic link ownership
to not be changed.
