SSL certificates with SAN domain names with uppercase characters will fail to match SNI requests for that domain name.
SNI does not match, resulting in the wrong certificate being returned to the client, which potentially results in a security warning in the client application due to a non-matching domain.
Multiple client-ssl profiles configured with SNI associated with a single virtual where the SAN (Subject Alternative Name) contains DNS names with uppercase characters.
Use lowercase characters for SAN domain names in SSL certificates.
SNI match is now case-insensitive.
