tls question
by Borresen, John - 0442 - MITLL
All,
Can the
olcTLSCACertificateFile
and
olcTLSCertificateFile
be the same file? Finding some "interesting" examples online (even on some openssl.org pages) and would like clarification.
Thanks,
John

I would sys you delete all certificates and certificate database files and restart from scratch. If you are using the openssl CA tools in order to create certificates, /etc/ssl/openssl.cnf should be modified to meet your requirements (in particular FQDN). Run ./CA.pl -newca ./CA.pl -newreq ./CA.pl -sign openssl rsa -in nrewreq.pem -out myKey.pem mv newcert.pem host.pem ./CA.pl -verify host.pem
