You also have a choice to set multiple IDPS for Single Application. And there are two ways to represent them :
- Login using IDP selection page: gives user an option to Select IDP from dropdown list during login time.
- Domain Mapping: Here we map the email domains to particular IDP. So when the user enters the Email address with specific domain he would be redirected to Respective IDP.
- App Identity Provider Mapping: gives user an option to Select one specific IDP for their application before login.
Note :At once you can select either of them.
