Aloha. We are trying to get OCSP verification working with RHEL 8 SSSD. The OCSP responder CA is not in the trust chain of the CA that issued the smart card certificates. I was able to get openssl ocsp verification to work using "-verify_other" and "-trust_other" options.
[root@c27nmgmtjtprlh1 PKI]# openssl ocsp -issuer DOD_ID_CA-63.pem -verify_other NAWEPRLHRD12.pem -trust_other -cert ~alvareza/alvarez.pem -url http://repeater1.xxxxx.xxxxx.xxxx.xxxx.xxxx -respout -text WARNING: no nonce in response Response verify OK /home/alvareza/alvarez.pem: good This Update: May 9 00:00:00 2024 GMT Next Update: May 15 06:16:18 2024 GMT
I tried to perform OCSP verification with the SSSD p11_child helper, but it does not work. Does anyone know if the "Direct Trust" model for OCSP works with RHEL 8 SSSD?
