Hi Martin and Martin,

last week I have identified an incompatibility between Dogtag's sslget
command and Apache HTTP. sslget sends a server name indication during
the TLS/SSL handshake but doesn't send a HTTP Host header. Newer
versions of Apache HTTP don't accept requests with SNI and without HTTP
Host. You should see a HTTP/400 Bad Request in /var/log/httpd/error_log.

The simplest workaround is to bypass Apache and talk to Dogtag directly.
In order to do bypass the Apache proxy you have to log onto the server.
You also have to become root so you can access the NSS database that
contains the private key for authentication. Simply copy and paste the
sslget command from the log (everything between "Command '[" and "]'
returend non-zero exit status 6!"), remove the comma, replace
'ipa.home:443' with 'ipa.home:8443' and run the command. The command
should look like:

'/usr/bin/sslget' '-n' 'subsystemCert cert-pki-ca' ...
'/ca/agent/ca/updateDomainXML' 'ipa.home:8443'
