Subject: [users@httpd] 2.4.9 expecting DH PARAMETERS
To: "" <>

When upgrading from 2.4.7 to 2.4.9 we found that the server complained
about missing DH PARAMETERS in our certificate and would not start.  Adding
dhparams to it fixed it.  After some troubleshooting we found that only
systems that did not have SSLCertificateChainFile directives with the
intermediate certificate exhibited this problem.  Combining the server and
intermediate certificates into the SSLCertificateFile also required adding

OS is RHEL5, using distro provided openssl (0.9.8e).

Is this a bug or am I doing something wrong?
