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 is created as a clone of upstream ticket:
https://fedorahosted.org/freeipa/ticket/5463

Method: get_ipa_config() in ldap2.py does not work as expected.
The ipaconfig values are not cached and method always asks directly LDAP server.

The issues is that the *is* operator return false even if the connection is the same as was before. 
{{{
        try:
            config_entry = getattr(context, 'config_entry')
            if config_entry.conn is self.conn:
                return config_entry
        except AttributeError:
            # Not in our context yet
            pass

}}}

fixed upstream

master:
    7f0d018c66da1fe2adedd45aa9f5a63c913e4527 fix caching in get_ipa_config 

ipa-4-2:
    0ca4c1db3ee6d9366f447d0d704fa56d98e366b4 fix caching in get_ipa_config

Causes that IPA command performs additional ldap search for server config for every ldap search done in the command. E.g., in user-add it is additional 12 searches. 

This has slight performance impact.

Verified.

IPA server version::

ipa-server-4.4.0-5.el7.x86_64


Steps to verify ::

1. Fresh install ipa-server
2. Add IPA user 
3. tail DS access log, usually found /var/log/dirsrv/slapd-<INSTANCE>/access
4. perform operations like 'ipa user-show', 'ipa user-find' and 
5. Grep for string in DS access log
 {{
"SRCH base="cn=ipaconfig,cn=etc,dc=example.com" scope=0 filter="(objectClass=*)" attrs=ALL" 

}}

6. Note that this string should appear once for each request / connection of ipa command.
