Yes, because nameConstraints are inherited. I don't know exactly where the bug lies but I strongly advise NOT to use nameConstraints because while there is a standard nobody has implemented full or correctly working support for it. I ran various tests some weeks ago and the result was horrible. See https://mta.openssl.org/pipermail/openssl-users/2015-May/001387.html and https://mta.openssl.org/pipermail/openssl-users/2015-May/001388.html 2015-06-29 23:58 GMT+02:00 David Li <dlipubkey at gmail.com>: > The subCA has nameConstraints in the subCA configuration file: > > [name_constraints] > permitted;DNS.0 = example.com > > client configuration file has subjectAltName: > subjectAltName = DNS: www.cs.com > > So is this a mismatch?
