Microsoft Entra and IRIS

Dear All,

I am currently part of a team that is developing an application using Microsoft PowerApps as the front end and IRIS as the backend.  Effectively that frontend screens, which are house and an Azure serve, call a series of REST interfaces exposed by IRIS from a physical Microsoft server.  During the development stage we have not had any security in place but now we need to secure the application using a single sign on.  PowerApps relies on Microsoft Entra for its security both LDAP and OAuth.  Has anyone in the community connected IRIS to Microsoft Entra? 

I have managed to register register the REST endpoints in Microsoft Entra as an application hence have a ClientID and so on.

Any help would be much appreciated.

Regards

Brad
