OpenSSL 0.9.8 before za didn't send an unecognised name alert and its
behaviour was inconsistent with 1.0.0 and later. The change fixed this.

Apache 2.2 specificically tells openssl to return an unrecognized name alert
but due to the bug in 0.9.8 this wasn't actually done. If you'd used 2.2 with
OpenSSL 1.0.0 or later you'd have seen this earlier.

Apache later than 2.4 no longer tells OpenSSL to send the alert.

I'd suggest you update Apache so it no longer returns
SSL_TLSEXT_ERR_ALERT_WARNING.
