Multiple IDP's from the same Azure Tenant to a Single SN Instance

[Joe B2]

We have a requirement to have a new custom URL within our ServiceNow instance which will point to a new portal. This is due to part of the organisation moving over to another company however the users will continue to use the same SN instance WITHOUT domain separation.

The new portal URL works fine but due to it being a completely different URL/Domain users are required to login again when swapping from one URL to another. This is fine for anyone with a local user account but we also have a number of different SSO users from multiple tenants.

For this to work we need to create a new Azure IDP with an end point to the new portal URL. The setup for this has been done however when attempting to create the IDP in ServiceNow we get a unique key violation. This appears to be because the app in Azure has the same ID no matter which end point URL it is pointing at.

We cannot simply point the existing SSO to the new portal as the SSO users have need to use URLs.

Has anyone encountered this before or has any idea how to allow multiple SSO connections from the same Azure tenant into the same ServiceNow instance?

Ultimately this isn't possible as it's still the same instance underneath and the same source tenant.

We went for a different approach and had these users land on a portal selection screen so they could select where they wanted to go after login.
