This can +# furtherly be used by services in order for proper certificate revocation to +# come into effect. The class also sets up a cron job that will refresh the CRL +# once a week. Also, processing of the CRL file might be needed. e.g. most CAs +# use DER format to distribute the CRLs, while services such as HAProxy expect +# the CRL to be in PEM format. +# +# === Parameters +# +# [*crl_dest*] +# (Optional) The file where the CRL file will be stored. +# Defaults to '/etc/pki/CA/crl/overcloud-crl.pem' +# +# [*crl_source*] +# (Optional) The URI where the CRL file will be fetched from. +# Defaults to undef +# +# [*process*] +# (Optional) Whether the CRL needs processing before being used.

This is because most CRLs +# by default come in DER format, so most likely it needs to be transformed. +# Defaults to true +# +# [*crl_preprocessed*] +# (Optional) The pre-processed CRL file which will be transformed. +# Defaults to '/etc/pki/CA/crl/overcloud-crl.bin' +# +# [*crl_preprocessed_format*] +# (Optional) The pre-processed CRL file's format which will be transformed. +# Defaults to 'DER' +# +# [*minute*] +# (optional) Defaults to '0'. +# +# [*hour*] +# (optional) Defaults to '1'. +# +# [*monthday*] +# (optional) Defaults to '*'. +# +# [*month*] +# (optional) Defaults to '*'. +# +# [*weekday*] +# (optional) Defaults to '6'. +# +# [*maxdelay*] +# (optional) Seconds.
