When registering a new Azure Provider with Azure in the SMP Console, we get the error:
The 'https://SMPserver:4726/altiris/console/authcallback/' redirection URL must be registered for the specified cloud application
The port 4726 did not match what was registered with Azure. It may be that the user set port 4726 by mistake and port 443 should have been used, or the SMP uses port 4726 by default.
