I am currently working on MDM 220.127.116.11. We have installed mutually authenticated certificates between the WAS server (on which MDM is deployed) and other applications that consumes these MDM services. Hence my application security is disable on WAS. THis setup was working fine and upstream applications were able to consume the MDM services. Once we enabled SAM logging, we started getting exceptions in our logs, saying that "UNAUTHENTICATED_USER". Can someone kindly provide some help on how to resolve this issue?
