Dear pki-users.
I'm trying to setup a pki-ca instance to produce X509 certificates which include a
Subject Alternative Name Extension with the following attributes:
Criticality = not critical
Type = RFC822Name
Value = the email of the requestor.
I'm using the Signed CMC-Authenticated User Certificate Enrollment profile and this
is the relevant section of my /var/lib/pki-ca/profiles/ca/caFullCMCUserCert.cfg file:
policyset.cmcUserCertSet.8.constraint.class_id=extensionConstraintImpl
policyset.cmcUserCertSet.8.constraint.name=Extension Constraint
policyset.cmcUserCertSet.8.constraint.params.extCritical=false
policyset.cmcUserCertSet.8.constraint.params.extOID=2.5.29.17
policyset.cmcUserCertSet.8.default.class_id=subjectAltNameExtDefaultImpl
policyset.cmcUserCertSet.8.default.name=Subject Alternative Name Extension Default
policyset.cmcUserCertSet.8.default.params.subjAltExtGNEnable_0=true
policyset.cmcUserCertSet.8.default.params.subjAltExtPattern_0=$request.requestor_email$
policyset.cmcUserCertSet.8.default.params.subjAltExtType_0=RFC822Name
policyset.cmcUserCertSet.8.default.params.subjAltNameExtCritical=false
policyset.cmcUserCertSet.8.default.params.subjAltNameNumGNs=1
The input certificate request is generated using certutil and CMCEnroll and the command
used is the following:
certutil -R -g 2048 -s "<the-subject>"
-7"<the-requestor-email>" -d<a-local-dir> ……
The certificate is generated, but the extension is not populated with the email address
and I always get:
Identifier: Subject Alternative Name - 2.5.29.17
Critical: no
Value:
RFC822Name: $request.requestor_email$
Hello,
In short, the email is not being looked at because
$request.requestor_email$ is created through the WebUI through an input
box (Requestor Email). See [1] for some more variables. You may want
to configure the caFullCMCUserCert to copy all subjAltNames in the input
to the output certificate using the User Supplied Extension Default
(with 2.5.29.17 as the argument):
"This default populates a User-Supplied Extension (2.5.29.17) to the
request."
