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.

+++ This bug was initially created as a clone of Bug #1367026 +++

Description of problem:
Prepare, document and test a procedure for configuring IdM Server (FreeIPA) by enabling only ciphers TLS 1.2 or stronger.

This procedure will ensure that:
- all primary IdM components (ipa-server, 389-ds-base+openldap, pki-core+tomcat, httpd+mod_nss, krb5-server, sssd) support TLS 1.2 and can be configured to only support that cipher suite or stronger.
- Administrator has a procedure to strengthen IdM cipher suite in case a vulnerability similar to POODLE (IdM Bug 1154687) emerges and allowed ciphers become vulnerable.

There isn't any document for RHEL 7. Do we need one?

Since there are some differences in the configuration, I think we should have a guide for RHEL 7. From development perspective, it would be a minor effort - simply testing the steps mentioned above.

This is the original documentation from RHEL-6.9:

~~~~
IdM servers can now be configured to require *TLS* 1.2 or better

Version 1.2 of the Transport Layer Security (TLS) protocol is considered significantly more secure than previous versions. This update enables you to configure your Identity Management (IdM) server to forbid communication using protocols that are less secure than *TLS* 1.2.

For details, see the following Red Hat Knowledgebase article: https://access.redhat.com/articles/2801181.

We need similar documentation and steps for RHEL-7.x.
