OK, after battling a little bit with this issue, I configured both the Apache EPPD module
configuration file and three registrars with their appropiate certificates. For this
testing I used
http://cacert.org/; this CA is included in the ca-certificates package.
I'm documenting all this in my Blogger entry. I'm telling you where to look for
this documentation, which includes using your own CA and using an external CA.
As far as I can tell there is one thing that should be taken into account. The CA must be
the very same both for the EPPD module and for the registrars. Each of these entries
should have their own certificates.
Feel free to comment about it.
Best regards.
