In the smb.conf file, what does the %S variable mean?

The session username is typically represented by variables like `%U` (current user) or `%u` (if different from `%U`).

The name of the Samba server is usually derived from the machine's hostname or explicitly set with the `netbios name` parameter.

In Samba's `smb.conf` file, `%S` is a special variable that expands to the name of the current service (share) that the client has connected to. This is useful for configuring share-specific behaviors, such as logging or path manipulation, within the global or a specific share section.

The local IP address to which the client connected is not directly represented by `%S`.
