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-1.3.9.1-3.el7
Doc Type: Bug Fix
Doc Text:
Cause: When there are already heavily nested group memberships, and you perform a modrdn, it is possible that entry was already a member of a group. Consequence: The modrdn operation is incorrectly rejected Fix: Do not reject the operation if the entry is already a member of the group the memberOf plugin is trying to update Result: Modrdn operations are not rejected if the memberOf plugin has already applied the update.

Comment 5 mreynolds 2019-02-23 12:14:47 UTC 
This issue is being addressed in:

https://pagure.io/389-ds-base/issue/50236   --> this is the cause of the error 1, which then triggered ticket 50238

https://pagure.io/389-ds-base/issue/50238   --> this is the cause of the error 32 following the modrdn failure

Both of these have fixes that are currently under review...

Comment 11 mreynolds 2019-03-16 02:49:19 UTC 
Well there are two issues


[16/Mar/2019:00:18:16.983850679 +0200] conn=395 op=1 MODRDN
dn="cn=supercr1,cn=groups,cn=accounts,dc=testrelm,dc=test"
newrdn="cn=new_group1" newsuperior="(null)"
[16/Mar/2019:00:18:16.985220682 +0200] conn=395 op=1 RESULT err=53 tag=109
nentries=0 etime=0.0001457309

This above kind of seems expected, but I need to look into it more, but this below:

[16/Mar/2019:00:18:17.663309849 +0200] conn=396 op=1 MODRDN
dn="cn=supercr1,cn=groups,cn=accounts,dc=testrelm,dc=test"
newrdn="cn=new_group1" newsuperior="(null)"
[16/Mar/2019:00:18:17.664447318 +0200] conn=396 op=1 RESULT err=68 tag=109
nentries=0 etime=0.0001222326

This looks like entry cache corruption which is exactly what we thought we just "fixed".   

Is there a system I can look at where this is reproducible?
Comment 12 Lukas Slebodnik 2019-03-16 17:21:08 UTC 
Test passed for me after removing patch
0006-Ticket-50260-backend-txn-plugins-can-corrupt-entry-c.patch
from spec file.
Comment 13 mreynolds 2019-03-17 12:38:56 UTC 
Lukas,

If you could set up a fresh install (with the fix for 50260 in place), and send me the exact command to reproduce the error that would be great!!!  

Thanks,
Mark
Comment 14 mreynolds 2019-03-17 13:07:03 UTC 
Hi Lukas,

Actually looks like I reproduce the issue now in my CI test!!  One quick question, the error 53 (unwilling to perform) that is the expected error message correct?  The problem is that on the second attempt the error changes to ALREADY_EXISTS?

Thanks again,
Mark

I am fine with workaround which I found (removing 0006-Ticket-50260-backend-txn-plugins-can-corrupt-entry-c.patch)

I let QEs to prepare reproducer mentioned in comment 2.

Just a note there is another BZ1689585 which make it more difficult to reproduce on el7.7.
They might need rhel7.6 + 389-ds from rhel7.7

Well I found the root cause of the last failure.  The fix for 50260 was previously not checking all the hashtables in the cache.  I have fixed this, and it is now under review...

I was planning on adding this fix to the next 7.6 batch update, but I'm not sure what's is going on with the other bug (BZ1689585) - not enough info to know it's related to this or not (looks like CS issue, but I could be wrong)
