FreeIPA still conflicts with mod_ssl. However, it should now be able to live next to that, as per https://bugzilla.redhat.com/show_bug.cgi?id=761574.

I tried to just remove the Conflict, but receive an error:

Rob's advice:

The call to disable_ssl is still done in httpinstance.py. It backs-up and removes ssl.conf which is probably why there is no SSLCertificateFile. Still, it is surprising that SSLEngine is even enabled.

I'd check to see if /etc/httpd/conf.d/ssl.conf exists. If not, uninstall IPA server which should restore it, then disable the mod_ssl disable call and see if the install succeeds then (we probably need to remove this call anyway).

Optionally, install mod_ssl post IPA-installation.

Fixing description formatting.

I have a candidate patch prepared during investigation.

Autotriaging to 3.3.x, it is a required fix for this release.

We have now all the bits in Fedora (http://koji.fedoraproject.org/koji/buildinfo?buildID=473624)


  1. Install newest mod_nss
  2. Install patched freeipa
  3. Install mod_ssl
  4. Update /etc/httpd/conf.d/ssl.conf to not listen on 443, but rather on 10443 or others
  5. "setenforce 0" to allow httpd listen on that port
  6. ipa-server-install

The server should now listen on both 443 with mod_nss and 10443 with mod_ssl. CLI and Web UI should continue to work, as well as cert operations like "cert-show 1" - cert operations would not work if new mod_nss is not updated.
