A standalone Samba server is an implementation that is not a member of a Windows NT4 domain,
a Windows 200X Active Directory domain, or a Samba domain.
By definition, this means that users and groups will be created and controlled locally, and
the identity of a network user must match a local UNIX/Linux user login. The IDMAP facility
is therefore of little to no interest, winbind will not be necessary, and the IDMAP facility
will not be relevant or of interest.
