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.
Installing an IdM replica on RHEL 7.6 fails if the IdM master runs on RHEL 6
With the update of the pki-core package provided by the RHBA-2019:XXXX advisory, certain ciphers are no longer enabled by default in the Identity Management (IdM) Certificate Authority (CA). As a consequence, setting up an IdM server with integrated CA on RHEL 7.6 as a replica of a master running on RHEL 6 fails with a "CRITICAL Failed to configure CA instance" error. To work around the problem, append the following entry to the end of the NSSCipherSuite parameter in the /etc/httpd/conf.d/nss.conf file:
+ecdhe_rsa_aes_128_sha,+ecdhe_rsa_aes_256_sha
As a result, the IdM installation on RHEL 7.6 no longer fails. Note that installing a CA-less IdM replica on RHEL 7.6 works as expected even without this workaround.

How reproducible:
Always
Steps to Reproduce:
1. Install IPA master on RHEL-6.10
2. Copy copy-schema-to-ca.py from 7.6 replica on Master and execute it
3. Generate replica gpg file on RHEL-6.10 master
4. Install replica on 7.6 replica with --setup-ca option
Actual results:
Replica install fails
Expected results:
Replica install should be successful
Additional info:
1. Replica install without --setup-ca option is successful
2. log files of pki instance are attached.
