Specifies a host name for certificate validation when SSL encryption is enabled (EncryptionMethod=SSL) and validation is enabled (ValidateServerCertificate=true). This property is optional and provides additional security against man-in-the-middle (MITM) attacks by ensuring that the server the driver is connecting to is the server that was requested.
Valid values
host_name
where:
host_name
is a valid host name.
Behavior
If host_name is specified, the driver compares the specified host name to the DNSName value of the SubjectAlternativeName in the certificate. If a DNSName value does not exist in the SubjectAlternativeName or if the certificate does not have a SubjectAlternativeName, the driver compares the host name with the Common Name (CN) part of the certificate’s Subject name. If the values do not match, the connection fails and the driver throws an exception.
Notes
If the HostNameInCertificate is not specified, the driver automatically uses the value of the ServerName from the URL as the value for validating the certificate.
If SSL encryption or certificate validation is not enabled, this property is ignored.
If SSL encryption and validation is enabled and this property is unspecified, the driver uses the server name that is specified in the connection URL or data source of the connection to validate the certificate.
If the HostNameInCertificate is not specified, the driver automatically uses the value of the ServerName from the URL as the value for validating the certificate.
