   @shinrich Yes, I believe a case-insensitive lookup would fix this issue. The Traffic Router, Apache HTTPD, and Nginx all seem to 1) lowercase the SNI and the certificate names (CN and any number of SANs present) before a strncmp() or 2) simply skip the lowercase step and use something like strncasecmp() for the comparison.  Given that DNS A/AAAA/CNAME... records are case-insensitive, it would follow that SNI lookups against certificate names in a CN/SANs should be case insensitive as well.
