I'll investigate the issue, but as I'm myself not using Fedora , that
will be more difficult. I'll setup a VM for that test.
Also, if python does cert validation (which I was hoping it was
already doing), I'd like to know why it complains about it, if you
have to point koji (through ~/.koji/config) to both ca and serverca.

Worth noting that we'll migrate "soon" (more details through the
cbs/infra weekly meeting) to FAS, so every CBS packager/builder will
have to modify his config.
We're also testing to offer different certs for koji communication :
the kojihub/kojiweb cert will be signed by a "trusted" CA (aka
serverca in your ~/.koji/config file) while FAS will be the CA used to
sign cert used for kojid builders nodes and koji client (so for "users")
