You can make the server require a client cert, but it won't use the
certificate identity for anything unless you Bind with SASL/EXTERNAL.
And naturally, if you're using SASL, then the DN/password pair is ignored.
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?
