BTW: In case of client certs the cert's subject-DN is the authc-DN which can be directly used in authz-regexp which very much ties the mapping to subject-DN conventions of the PKI. But in some cases it would be very handy to map a distinct client cert to a authz-DN by issuer-DN/serial or even by fingerprint. One use-case is cert pinning of client certs and revocation checking done off-line. Should I file an ITS for that? Ciao, Michael.
