[Pki-users] problem with OCSP setup

Hello, I'm trying to setup a Dogtag Certificate System. No problem to setup CA and OCSP in the same machine, but If I try to deploy OCSP on other machine I always get stalled in the same part of the configuration process: "Subject Names". There, I leave the default values of "OCSP Signing Certificate", "SSL Server Certificate" and "Subsystem Certificate" or even I change to other values. I pass to next step and setup the Admin password and finally the wizard come back to "Subject Names" screen, it's a endless process. In "catalina.out" file always appears: "Exception caught: java.io.IOException: Error: remote certificate is null" So it seems to be that OCSP doesn't received a certificate from CA. I have searched on Google but I can't find anything to end the OCSP process successfully. Does anybody known what it's happening with OCSP? Daniel Rodríguez.
