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.

Comment 3 Florence Blanc-Renaud 2023-01-12 17:01:16 UTC
The master installation has the following steps:

* [25/42]: adding default layout
This step creates cn=xx_id_range,cn=ranges,cn=etc,$SUFFIX with ipaBaseID and ipaIDRangeSize.

* [40/42]: activating sidgen plugin
This step creates the entry cn=IPA SIGEN,cn=plugins,cn=config with nsslapd-pluginenabled: on
At this point the plugin is enabled but skips any processing as there is no domain SID below $SUFFIX:
https://github.com/freeipa/freeipa/blob/5419864c7ef893abc4717847fa6ea272d0c659fe/daemons/ipa-slapi-plugins/ipa-sidgen/ipa_sidgen.c#L104
    if (ctx->dom_sid == NULL) {
        ret = get_dom_sid(ctx->plugin_id, ctx->base_dn, &ctx->dom_sid);
        if (ret != 0) {
            LOG("Domain SID not available, nothing to do.\n");
            ret = 0;
            goto done;
        }
    }

* [1/8]: creating samba domain object
This step creates the entry cn=$DOMAIN,cn=ad,cn=etc,dc=ipa,dc=test with ipaNTSecurityIdentifier=SID of the ipa domain.
From this point, the sidgen plugin is enabled and is able to find the domain sid, meaning it gets triggered for all ldap operations.
It starts by getting the RID ranges but the cn=xx_id_range entry doesn't contain ipaBaseRID or ipaSecondaryBaseRID and this is the cause for the error message:
ERR - get_ranges - [file ipa_sidgen_common.c, line 276]: Failed to convert LDAP entry to range struct.

* [3/8]: adding RID bases
This step adds the ipaBaseRID and ipaSecondaryBaseRID values to cn=xx_id_range, fixing the plugin issue.

It looks ok to call "adding RID bases" earlier but should be tested.

Anyway, the issue is really minor: if entries are created before the baseRID is added, they won't get a SID but the sidgen task is called later and generates the missing SIDs.

Comment 4 Florence Blanc-Renaud 2023-01-12 17:39:13 UTC
I am removing the Regression keyword as it's not a regression.

The installation of ipa server in RHEL 7.9 (ipa-server-trust-ad-4.6.8-5.el7.x86_64) with adtrust was already producing the same log. So the error has not been introduced recently.
