OCSP Responder
- Dec 09, 2020
Hi Lidev, thanks for responding...This is actually how I configured but I am not too sure if this is correct, however from the packet capture now I can see ocsp request and ocsp response already, I see we are hitting the remote ocsp. We don't want to use stapling but rather remote ocsp authentication but I am not too sure if I should enable the client authentication.
Would you be able to advise below if all are correct or if anything i missed?
- I created the "ocsp responder", this is where i put the "ocsp responder url".
- I created "ocsp configuration" and attached the "ocsp responder"
- I created "ocsp profile" and attached the "ocsp configuration"
- On the "application virtual server" I attached the "ocsp profile" under the "Authentication profile"
- On the "ssl client profile" of the application virtual server I have enabled the "client authentication", change "client certificate" from ignore to require and then apply the ca certificate under the trusted certificate authorities.
Test result:
- The moment user launch the url the browser prompt to select the certificate
- Select and click OK but page error
From the dump:
I see ocsp request and ocsp response and the status of ocsp response is "unaothorized".
From this point I can tell something wrong with the remote ocsp, however I want to know if my configuration are all correct.
Please, kindly advise. Thanks a lot.
Hi f5mkuDefault,
Your configuration seems to be fine and you can use either HTTP or HTTPs to request your OSCP Responder Server without any problem.
To validate the correct functionality of the OCSP Responder, check OCSP Reponse Status (successful (0x0) and if the Next Update extension is present in your OpenSSL command output.
You can aslo check the OCSP statistics on your F5 BIG-IP :
show sys crypto cert-validator ocsp <profile_name>
Regards
hi Lidev, actually it is not working. even the show crypto does not work, so I am not sure if I missed something.
Is there some configuration I need to do on the SSL Profile?
