[Wed Aug 20 08:05:33.208723 2014] [ssl:warn] [pid 3784:tid 256] AH01909: RSA certificate configured for www.example.com:443 does NOT include an ID which matches the server name
This means there might be a server name of foo.example.com
but the certificate is for bar.example.com
only. In that situation, while Apache might try to serve such certificate, the browser s will not accept them when accessing https://foo.example.com
, for instance.
