Because, if we take login, logged into the resident IdP does not mean that you are also logged into the federated IdP as well. So if you try to login to SP2 in above case, you will get the login page from the federated IdP. So, should it be that logging out from the resident IdP only, should log out the user from the federated IdP as well. Which is the case you have mentioned above. I think, we should notify only the session participants of the current IdP session. > > >> >>>>> Thanks. >>>>> >>>>> Regards, >>>>> *R.
