AT-TLS support for limiting which client certificates that are allowed to use an specific IP port

We need to be able to use AT-TLS with client and server verification of certificates.
We need to be able to limit which client certificates we allow to connect and use this IP port so that not all certificates from a CA in our truststore (keyring) is allowed.
We plan to use this feature in conjunction with IMS Connect, the purpose is to be in control and know exactly which application (on certificate base) we trust to connect to IMS Connect on this specific IP port.

    I support this request. We have an similar scenario with a remote client promoting at application level pre-authenticated user information without full credentials to a z/OS task over an AT-TLS connection, and therefore requiring this client to be trusted by z/OS. We need the RACF user id derived from the client's certificate to be checked whether it is allowed for the connection. Since we have a requirement to use AT-TLS for TLS support wherever possible (central management, up-to-dateness), we need to make AT-TLS check this. I suggest to extend the SAFCheck option of ClientAuthType by a new parameter safname. AT-TLS might then check SAF profile, e. g. EZB.ATTLS.sysname.tcpname.safname of class SERVAUTH, for READ access with the user id derived by SAFCheck from the certificate and then allow or close the connection with regard to the RACF return code.
