active STS callbacks knowing the endpoint invoked (by Office 365)


Allowing the endpoint URI configured in Office to select a particular “tenant’s” active STS, using parameters placed after the formal endpoint name.

e.g.  metadata exposes, but

office SP would use

The trick is to let attribute the STS callback classes with a service behavior that an capture that endpoint URI actually cited by Office SP – so it can then switch to per-tenant configuration parameters.
