Would like to be able to enable SSO for multiple Azure AD instances. We have multiple companies under one parent company but still operate within different M365 environments.
@nathankerr is the parent company acting like a MSP to all the other companies? Does each company have their own IT team or does it all roll up into a centralized services team? Do the multiple companies work with each other or are they just owned by the parent company and run on their own? I am asking because we are working on a MSP model for SWSD that will support each company having their own SWSD tenant but all the incidents will roll up to the MSP account for federated management/view. Thinking it might be something that would work for your situation.
Each company has its own M365 tenant, but we are now synced through a cross-tenant connection established in the parent company environment. We can see each other's Teams, calendars, SharePoint, etc. Currently, each company has its own IT team, but we are going to centralize IT services soon and would want a common place for all PC techs to see and get assigned tickets. Regardless of what domain a user has we want them to be able to take advantage of SSO
