Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Topology diagram with 12 servers

Describe what we recommend as replication typologies.

Here are several principals that need to be followed:

1) Put IPA servers into each of your main data centers.
If you have a small branch office you might put a replica there to or it can be connected using SSSD caching capabilities.
2) We recommend at least 2 servers per data center
3) We do not recommend more than 4 servers per data center
4) Each server should have replication agreements with at least two other servers so that if one of the servers goes down there are no orphans.
5) The recommended number of the replication agreements per server is 2-3. 4 is maximum recommended
6) The rules above lead to "cell based" configuration when a set of servers form a cell of more tightly replicated servers and then the cells are loosely coupled to each other.

The attached diagrams show the potential configuration. They are just an example that illustrates the rules and principles described above.

Mass closure. These bugs were live in RHEL 6.5.
