I tried it and found out it can't work this way - when issuing a CSR

parameters  and pass them to the proxy-shellscript. Only the -u
paramter is known beforehand, as it is configured in the ca description
file or in the proxy shellscript itself.
On systemd-enabled systems certmonger runs as a service. You can affect
the environment of the service by adding files ending in .conf in
/etc/systemd/system/certmonger.service.d/

See systemd.service and systemd.unit man pages.

Hi,

i have to access an external PKI server with SCEP protocol through our
corporate proxy.  On command line I can set the proxy and trigger a
CSR with the scep-submit helper successfully.

What are you setting, environment variables I assume?

But same operation with getcert fails, as there is no proxy
configuration possibility in e.g. certmonger.conf.

How can I work around this ?

A quick kludge might be to replace scep-submit with a shell script that exports 
the proxy config and then calls the real scep-submit.

A perhaps better and more supportable idea would be to add a CA pointing to 
this new helper, something like:

getcert add-ca -c exampleSCEPca -e \
    "/usr/libexec/certmonger/scep-submit-proxy -u 
http://ca.example.com/cgi-bin/pkiclient.exe";

So scep-submit-proxy would setup the environment and call scep-submit.
