Dear, I have Root CA and Issue CA in my network. The issue CA is signed by the Root CA. Both these CAs are installed in CentOS 7 and Dogtag Version 10.5. Now I am going to Install the OCSP for the Issue CA. There is no OCSP for the CentOS 7, so I installed the OCSP  (10.8) in fedora. I tried to connect the OCSP to Issue CA with both Interactive and Manual configuration method. I still got an error. Error comes while tried to install the OCSP INFO: Loading subsystem config: /var/lib/pki/pki-tomcat/ocsp/conf/CS.cfgINFO: Checking existing SSL server cert: Server-Cert cert-pki-tomcatINFO: Creating temp SSL server cert for ocsp.mycompany.lkNotice: Trust flag u is set automatically if the private key is present.INFO: Joining existing domainINFO: Getting token for installing OCSP on ocsp.mycompany.lk Installation failed:com.netscape.certsrv.base.PKIException: error result Please check the OCSP logs in /var/log/pki/pki-tomcat/ocsp. There is no error shows in the log file. If I use the pkispawn it also generate the same error.
