Hi guys. I have a program that executes multiple parallel SAS sessions in Spre server of Viya (using "singon" feature) each SAS Session made a CAS connection and a CAS Session, but I need to configure the authfile info in the home directory on Spre Server. My question: is there an alternative to authfile configuration? because in this case, each user needs to configure the authfile and modify it every time credentials change. it's possible to use the login authentication or other forms automatically for the end user? Thanks!
