Prerequisites

If you have set up the hybrid deployment with LN UI 12.4.1 and you update to LN UI 12.4.2 (or later), the steps in Set up LN UI to use Single Sign On must be repeated to set a default configuration for Active authentication (WS-Trust Default Provider).

This is only required when you update from LN UI 12.4.1 to a later version and no longer necessary for subsequent updates (from 12.4.2 to later versions).

Also, the on-premises AD FS must be federated with Infor OS. To do this, see the steps in Federate the current OP ADFS with the Cloud Identity Provider.
