Multiple Office 365 tenants sign-on to one tenant


  • We have many companies under our main company umbrella. About 4000 total employees. About 30 companies ranging from 50-200 users each. The majority have unique local Active Directories. About half DirSync up to their own unique Office 365 tenants. We’d like to have all users authenticate to a single SharePoint online site at the main corporate tenant, without having to add all the users via external sharing. Is SSO the only answer here? Whether it’s ADFS or Okta? Or can AADS help us? Would this be made any easier if SharePoint was on premise?
