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.

Fixed In Version: 389-ds-base-1.3.7.5-5.el7
Doc Type: Bug Fix
Doc Text:
Directory Server no longer logs an error if not running the "cleanallruv" task After removing a replica server from an existing replication topology without running the "cleanallruv" task, Directory Server previously logged an error about not being able to replace referral entries. This update adds a check for duplicate referrals and removes them. As a result, the error is no longer logged.

Description German Parente 2017-03-21 10:07:02 UTC 
Description of problem:

This problem was fixed in:

https://bugzilla.redhat.com/show_bug.cgi?id=1288229
many attrlist_replace errors in connection with cleanallruv

but has re-appeared in this new version. I know it's harmless but it's preventing to read the logs and to find information.

I have checked the patch in:

https://pagure.io/389-ds-base/issue/48283

and it's included in the master branch.


Version-Release number of selected component (if applicable): 

389-ds-base-1.3.5.10-15.el7_3.x86_64


How reproducible: in lots of customers and even locally when there are invalid ruvs.

German, how do you reproduce this exactly?  Thanks!
Comment 10 mreynolds 2017-05-04 15:08:20 UTC 
Closing for now until a reproducer is found
Comment 11 German Parente 2017-09-18 14:35:36 UTC 
We are seeing these errors again in all the customers.

in 7.4 version.

Please, investigate this because customers are asking support to clean the ruvs all the time only because of these errors.

Or eventually, log a warning since it's not an issue.
Comment 12 Viktor Ashirov 2017-09-18 17:23:03 UTC 
Re-opening per c#11 for investigation.
Comment 14 Ludwig 2017-09-22 08:56:22 UTC 
bug 1288229 fixed a real bug in managing nsds50ruv  with many elements which could lead to invalid duplicate values and as a consequence to attrlist_replace errors for nsds50ruv attribute.

This bug is about nsslapd-referral and I think it is not a real bug, but a consequence of bad RUVs. I have not yet written a reproducer, but from my analysis I think this is what happens.

In a replication session the nsslapd-referrals in the mapping tree entry are updated based on the supplier ruv.
The nsslapd-referral only uses the URL ignorig the replicaid
If a ruv contains the same URL with different replicaids the generated list of referrals will contain duplicate urls and so lead to the attrlist_replace error.

Cleaning the RUV should prevent further occurrence of these messages.

But we could enhance the replication code to strip duplicate urls before updating the referrals, hiding problems with invalid ruvs
