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.

Doc Type: If docs needed, set a value
Doc Text:
Cause – ipa-cacert-manage renew --external-ca generates a CSR that does not contain the Basic Constraint CA: TRUE Consequence – the signing CA needs to add the constraint to the CA certificate it issues otherwise the resulting CA certificate will be invalid Fix – The Basic Constraint CA:TRUE is added to CSRs generated for the CA Result – The resulting CSR has appropriate constraints for a CA certificate

version:
ipa-server-4.5.0-22.el7_4.x86_64

steps:

1. Install master with selfsigned CA

2. Generate a csr to be signed by external CA 
       - ipa-cacert-manage renew --external-ca

3. Check for CA value in csr generated in 2
       - openssl req -in /var/lib/ipa/ca.csr -noout -text|grep CA

4. Sign the csr generated in 2 by external CA

5. Renew the CA with external CA cert and signed cert
       - ipa-cacert-manage renew --external-cert-file=/tmp/external.crt --external-cert-file=/tmp/ca_signing.crt

6. Check for CA value in signed cert and external cert

       - openssl x509 -in /tmp/external.crt -noout -text|grep CA
       - openssl x509 -in /tmp/ca_signing.crt -noout -text|grep CA

Expected result:
CA value should be TRUE

Actual result:

Master:

[root@master ~]# openssl req -in /var/lib/ipa/ca.csr -noout -text|grep CA
                CA:TRUE

[root@master ~]# openssl x509 -in /tmp/external.crt -noout -text|grep CA
