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.

Description Nikhil Dehadrai 2016-10-04 11:52:09 UTC 
Description of problem:
ipa config-mod returns "Configured size limit exceeded" while modifying searchrecordslimit value.

Version-Release number of selected component (if applicable):
ipa-server-4.4.0-12.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Setup IPA on latest 7.3 version.
2. Install Latest version of IPA server to it. 
3. Execute following commands:
# kinit admin

4. Now execute: 
# ipa config-mod --searchrecordslimit=0

5. Run:
# ipa config-mod --searchrecordslimit=1

6. Finally:
# ipa config-mod --searchrecordslimit=2

7. Now run:
# ipa config-show

Actual results:
After step6 and step7, Configured size limit exceeded message is displayed.

Expected results:
No error should be returned, and the modified value should also be set
Comment 2 Martin Bašti 2016-10-04 11:57:59 UTC 
This is caused by postcallback that is searching for server roles and reach size limit.

IMO we should not apply sizelimit on internal searches

Comment 7 Petr Vobornik 2017-04-06 16:08:33 UTC 
IdM team doesn't have capacity to fix this bug for RHEL 7.4. Moving to next RHEL version. Fixing the bug there will depend on capacity of FreeIPA upstream. Without sufficient  justification there is a chance that it will be moved again later.
Comment 10 Armando Biagioni Neto 2018-06-18 15:12:31 UTC 
Unlinking from upstream ticket https://pagure.io/freeipa/issue/6383 because this is only going to address the issue where a user can set a value too low and get stuck.

    59e0c02 ipaserver config plugin: Increase search records minimum limit
Comment 14 Nikhil Dehadrai 2018-07-18 12:17:22 UTC 
ipa-server-version: ipa-server-4.6.4-2.el7.x86_64

Verified the bug on the basis of following observations:
1. Verified that with latest version minimum 'searchrecordslimit' must be at least 10. If we set any value which is either less than '-1' or between '1 to 9' appropriate message is returned.

Console:
[root@ipaqavmf ~]# rpm -q ipa-server
ipa-server-4.6.4-2.el7.x86_64

[root@ipaqavmf ~]# ipa config-mod --searchrecordslimit=-2
ipa: ERROR: invalid 'searchrecordslimit': must be at least 10

[root@ipaqavmf ~]# ipa config-mod --searchrecordslimit=1
ipa: ERROR: invalid 'searchrecordslimit': must be at least 10

[root@ipaqavmf ~]# ipa config-mod --searchrecordslimit=2
ipa: ERROR: invalid 'searchrecordslimit': must be at least 10
