O Firefox tem uma nova política que os certificados emitidos após 2016-08-23 precisam ter um campo SubjectAltName.
Nosso administrador criou um novo certificado para o nosso servidor rt. Desde então, recebo um erro SSL_ERROR_BAD_CERT_DOMAIN no Firefox. No entanto, o site funciona a partir do Chrome e curl.
O certificado é assinado por nossa CA interna (freeipa), para a qual instalei o certificado público em minha máquina. Outros sites assinados por nossa CA interna funcionam corretamente.
Aqui está a informação de depuração do Firefox:
https://rt.lsd.co.za/
Unable to communicate securely with peer: requested domain name does not match the server’s certificate.
