Some of this is covered in https://bugzilla.redhat.com/show_bug.cgi?id=1178540. Opening a ticket here to cover that plus some other items.

There is a missing requires on httpd. The ipsilon-server-install clearly has a dependency on httpd.

Likewise ipsilon-server-install writes the ipsilon-ipa.conf httpd config file and inserts SSLRequireSSL, but this httpd config option is only available if mod_ssl is installed, if mod_ssl is not installed then when you start httpd it will abort because of an undefined option.

Thus there is a missing requires on mod_ssl.

Bug #1178540 discusses the missing dependencies on freeipa-client and freeipa-admintools. Addressing this probably requires adding an ipa subpackage to ipsilon. Note if you specify --ipa to ipsilion-server-install and freeipa-admintools is missing all you get is a cryptic traceback.

This issue ticket was originally removed from the tracker as it clashed with the pull request.
