[openssl-users] How to verify a cert chain using Openssl command line?

[David Li]

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? How come s_client/s_server test was okay?
