Enhance z/OS Connect to fall back to basic authentication if certificate is for an unauthorized user

Currently it appears that if a program running in CICS does not specify to send a client certificate, CICS is then sending it's certificate to z/OS Connect.  In our case this ID does not have invoke access to the API so the attempt fails at that point.  We would not want to give the ID this certificate is associated with (CICS STC ID) access to z/OS Connect (or the z/OS Connect api) as it seems this would allow someone who should not have access to the api the ability to drive it without either a proper certificate or ID/Password.  So what we would like is if z/OS Connect authenticates a user via a digital certificate but then that ID does not have access to z/OS Connect EJBROLE (or whatever profile makes sense, could also be down to the API invoke level?) , that it would then fall back and allow basic authentication.

    Once a request has been authenticated, if it fails authorization, it is not possible to authenticate a second time using alternative credentials. The workaround in this instaance is to define two httpEndpoints in the z/OS Connect server, one that has client certificate authentication enabled and one that has only TLS enabled. The API can then be invoked over the second endpoint when basic authentication is required.

    We also added Idea CICSTS-I-2098 which is asking CICS for an option to not send the default certificate with the hope that z/OS connect will then drop down to the basicauth header. Please note that we must use SSL when sending a basicauth header as the credentials are only base64 encoded.
