I'm aware that this is a long shot but I'm in desperate need for someone who has experience in the constellation of communication server Telnet 3270 using AT-TLS with client cert authentication logging on to a CA-TPX with CA-ACF2.
Has anyone managed to implement Telnet 3270 ExpressLogon using AT-TLS with client cert authentication on CA-TPX with client certficates that have the ibmHostIdMappings extension? We currently use certificate mapping but we'd like to use ibmHostIdMappings in the future.
