Suppose one organization [OrgA] is using 2 Saas application services[OrgB and OrgC] . OrgB and OrgC is federating identity with OrgA ,using which employees of OrgA[Azure Active Directory] can single sign-on to the OrgB's Saas application [Resident IDP/Mediator] site and use their service. IN the same way OrgA's employees can access orgC's data OrgA ->trust relation ->OrgB OrgA ->trust relation ->OrgC
OrgB has tie up with OrgC and they provide inbuilt connector to OrgC so that they can share the data.OrgA buys a license to this connector, so that OrgB and OrgC can share the data of OrgA employees related to the service
OrgB ->trust relation ->OrgC Question
I understand the internals of establishing trust between 1 st layer of Third party services.But could not find any information on the following
How is OrgA's 4th Party[OrgC] is establishing trust with OrgB ,so that OrgB is able to share OrgA's data with OrgC?
What is the connector doing internally?[ Connector between OrgB and OrgC]
