We have on-prem SAP system that has been configured for SSO in Azure AD Enterprise App and is working, a Tile shows in the Azure App Access Panel / MyApps / O365 App launcher, which users can click on to get to it.
The SAP team are now asking if its possible to setup an additional application to appear in the App Access Panel that uses the existing Enterprise Application for SSO?
From my experience so far you cant add another Enterprise Application that users the Same SSO Identifier and if i setup an app registration using the URL they want to SSO to it just throws an error that is not very helpful.
"You cannot access this application because it has been misconfigured. Contact your IT department and include the following information: Undefined Sign-On URL for application "SAP - WebGUI"
Looking in the App Registration settings I cant see any where to configure the Sign-On URL...???
