Verifying certificate fields
When the first certificate is part of a chain, all the specified field values are checked in that certificate. If specified, the company name is also checked in all the other certificates, except for the root certificate. This arrangement allows for the case that the root certificate is held by a certificate authority. In this case, the field values of the root certificate will be different, as it is owned by the certificate authority, rather than your company or organization.
