SAML multi-instancing

Question

Hello

what is SAML multi-instancing ?? https://learn.microsoft.com/en-us/azure/active-directory/develop/configure-app-multi-instancing

Per doc, app multi-instancing refers to the need for the configuration of multiple instances of the same application within a tenant.

So does that mean that there would be SINGLE app-object and multiple Service-principal object for any SAML app pulled up from the gallery ??

Thanks.

@Sandeep G-MSFT you have copy-pasted the para from the public doc.

The real Question is, HOW ??

How are you going to create multiple service-principals for SINGLE application-object in your tenant ???

Yes, this means there will be one application registered in Azure AD and multiple service principals will be created for that application.

This is implemented when the organization has multiple accounts, each of which needs a separate service principal to handle instance-specific claims mapping and roles assignment. Or the customer has multiple instances of an application, which doesn't need special claims mapping, but does need separate service principals for separate signing keys.

This way you can configure multiple different claims for different service principal instance.

Let me know if you have any further questions.
