Subdomain wildcard certificate not recognized

gpin

We have created a self signed CA certificate that verifies a sub domain "*.dev.mydomain.example", NOT as in the more common case the whole domain "*.mydomain.example".

Firefox does not properly recognize a sub domain of this wildcard, e.g. cms.dev.mydomain.example.

The error message is:


cms.dev.mydomain.example uses an invalid security certificate. The certificate is only valid for *.dev.clearsense.at (Error code: ssl_error_bad_cert_domain)


using Firefox 36.0.4 on Mac OS X 10.9.5
