Hi Henri,

my fault - serialNumber is not in the "registered RDN" list for the template parser shortcuts, it should work with

preset: '[% serialNumer.0 %]'

best regards

I tried that, but it does not work.
Using the template with preset as set below, it fills serialNumber field
with value "serialNumber". Certificate profile is same as I presented
before. This sounds like a bug - maybe it tries to take key instead its
value?


serial.yaml:
id: serialNumber
label: serialNumber
description: Serial Number
preset: serialNumber
type: text
width: 40
placeholder: 0000

extensions

Hello Henri,

you have to use "serialNumber" as preset also, SN is the "Surname" OID :)

For the second part - you can turn on the "copy extension" flag but as
outlined in the comment this copies ANYTHING from the request so this
requires a certain portion of control on CSR generation and a very good
validation as you otherwise might sign things you do not expect too.

The other option requires a modification of the workflow and the use of
OpenXPKI::Server::Workflow::Activity::Tools::AddCertExtension, likely with
some magic around to build the right content - or an upgrade to the
enterprise edition which comes with a templating mechanism and some other
nice features around profile based extensions.

best regards

Oliver

I haven't been able to get any of that working. I added to templates
serial.yaml:

label: serialNumber

preset: SN.0

So far I've only tried the manual workflow. I can see it loads the
serial.yaml since it puts the placeholder data and labels in there,
but the serialnumber data from CSR is not filled.
For the custom OID I'm not that far yet since it fails to the serial.

Any idea what should be changed? Is the serial number even properly
supported?
