RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

https://fedorahosted.org/pki/ticket/1219
The dogtag certificate system will not produce certificates via scep for Juniper SRX 550 routers (OS version is JUNOS 12.1X46-D15.3) based on request submitted using ECC modules. When attempted, the following error is seen:

[12/Nov/2014:14:59:31][http-bio-8080-exec-8]: ServletException javax.servlet.ServletException: Failed to process message in CEP servlet: null
Steps t reproduce:
1. Install the Dogtag version 10.2.0
2. Enable router certificates in CS.cfg
change ca.scep.enable parameter to true
3. Adjust the router profile as follows:
The profile that needs to be changed is /var/lib/pki/pki-tomcat/ca/profiles/ca/caRouterCert.cfg
Currently if you look at the profile, by default the key constraint is limiting you to RSA
policyset.serverCertSet.3.constraint.class_id=keyConstraintImpl
policyset.serverCertSet.3.constraint.name=Key Constraint
policyset.serverCertSet.3.constraint.params.keyType=RSA
policyset.serverCertSet.3.constraint.params.keyParameters=1024,2048,3072,4096
You want to change it so that it accepts both RSA and ECC.
policyset.serverCertSet.3.constraint.class_id=keyConstraintImpl
policyset.serverCertSet.3.constraint.name=Key Constraint
policyset.serverCertSet.3.constraint.params.keyType=-
policyset.serverCertSet.3.constraint.params.keyParameters=2048,3072,4096,nistp256,nistp384,nistp521
4. Add the router IP and pin to the CA authentication file, /etc/pki/pki-tomcat/ca/flatfile.txt, e.g.:
UID:10.0.2.15
PWD:1212
2. Issue a request to the CA directly from the router and specify ECC as the key module and the one of the curves specified in the caRouterCert.cfg file.
The aforementioned error can be seen in the debug log of the CA.
Tests were done to make sure that the server could produce ECC certificates in general; both server and user certificates were produced using requests generated by openssl that were ECC based. We were also able to produce certificates via scep where the request was RSA based. The above scenario is the same whether the CA certificate is RSA or ECC based.
