Please share your ideas on the fastest way to implement this CA single sign on Task w.r.t. making the changes in authentication scheme for a different domain. Please share all the necessary steps (w.r.t, dns, ACO, etc,).
1. Currently we have an IWA server (Server111.abc.abcas.com) supporting IWA authentication for federation apps on a domain abc.abcas.com.
2. Now we want to use the same IWA server to extend IWA authentication functionality for a federation app on a different domain e.g. atsexternal.com.
Would request for complete steps as this is a very critical task for us.
