To do this, specify the following appsetting in the configuration file: If you temporarily cannot access correctly reissued certificates, you can choose to opt in or out of the security change to avoid any connectivity effects. Certificates that have no EKU extension continue to authenticate correctly.ДЇirst, consider making changes to your componentвЂ™s certificates to make sure that they are using the correct EKU OID attributes and are secured correctly. The object identifier for Server Authentication is 1.3.6.1.5.5.7.3.1. Likewise, when a certificate is used for server authentication, the object identifier for Server Authentication must be present in the EKU extensions of the certificate, or authentication fails. The object identifier for Client Authentication is 1.3.6.1.5.5.7.3.2. When a certificate is used for client authentication, the object identifier for Client Authentication must be present in the EKU extensions of the certificate, or authentication fails.

When certificates are used for authentication, the authenticator examines the certificate that is provided by the remote endpoint and seeks the correct purpose object identifier in Application Policies extensions. With this change, besides requiring the appropriate client/server EKU on certificates, if the root certificate is disabled, the certificate chain validation fails. Similarly, a certificate that is used for the authentication of a server must be configured for Server Authentication. For example, a certificate that is used for the authentication of a client to a server must be configured for Client Authentication. This extension indicates one or more purposes for which the certified public key may be used, in addition to or instead of the basic purposes that are indicated in the key usage extension.
