"ordinary" "wide links = yes" means the
server will follow symlinks on the file
system that point outside the root of the
share definition. If set to off (default),
the server will refuse to follow symlinks
that point outside of the root of the
share definition, but will follow symlinks
that point within the share.
If this is turned on, it disables SMB1
unix extensions (which allow symlinks
to be created by the client) unless
"insecure wide links" is *also* turned
