Issue/Introduction

ESM microservices server, used by Mainframe Team Center - Automation (MTC-A), uses TLS security, is it possible to use AT-TLS?
Is it possible to starting the server unsecure?

Environment

Release : 15.0

Component : EXTERNAL MICROSERVICE (ESM)

Resolution

ESM needs to use TLS directly.  It needs direct access to the keyrings because it needs to check that it trusts each client certificate directly, a requirement not enforced by standard TLS.  

ESM Microservice does not support AT-TLS currently.
