10.2. Using Online Certificate Status Protocol for httpd

Before you use Online Certificate Status Protocol for https, ensure you have configured httpd for SSL connections (see Section 9.1, “Configuring httpd for SSL connections”) as prerequisite.
To use Online Certificate Status Protocol (OCSP) for httpd, ensure that Certificate Authority (CA) and OCSP Responder is configured properly.
For more information on how to configure CA, see the Managing Certificates and Certificate Authorities section in the Linux Domain Identity, Authentication, and Policy Guide.
For more information on how to configure OCSP Responder, see the Configuring OCSP Responders section in the Linux Domain Identity, Authentication, and Policy Guide.

Note

The Certificate Authority must be able to append the following attributes to the Certificate: 
[ usr_cert ]
...
authorityInfoAccess=OCSP;URI:http://HOST:PORT 
...
[ v3_OCSP ]
basicConstraints = CA:FALSE
keyUsage = nonRepudiation, digitalSignature, keyEncipherment
extendedKeyUsage = OCSP Signing
Copy to Clipboard Toggle word wrap
Note that HOST and PORT will need to be changed to match your responder that you set up later.
