About Single-Role and Other Role Mapping Options
S4S provides an alternative to Multi-Role called Single-Role. This approach maps Sitecore roles to Salesforce Account names so any contacts that belong to an Account will appear in Sitecore as belonging to a Sitecore role with the Account name.

More options that involve some development effort are also possible with S4S.
