1129660 – [WebUI] Adding users to user group throws Internal server error.

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 7 Martin Kosek 2014-08-15 09:21:12 UTC

Thanks. This looks as intermittent errors, I could not reproduce them on my set up. I suspect that this may also be an Directory Server issue. Is there anything interesting /var/log/dirsrv/.../errors log?

Comment 8 Varun Mylaraiah 2014-08-17 17:52:25 UTC

I did not see anything interesting in /var/log/dirsrv/.../errors log. Also I have reproduced this bug on multiple machines.I have pasted the details of one of my machines in Comment 9 for your reference.
let me know if you need any further information.

Comment 10 Martin Kosek 2014-08-18 15:47:03 UTC

I see DS crashed, this is why it was not responding:

# grep ns-slapd /var/log/messages
Aug 18 01:07:46 server66ad ns-slapd: Failed to rename errors log file, Netscape Portable Runtime error -5950 (File not found.). Exiting...
Aug 18 04:32:54 server66ad kernel: ns-slapd[21240]: segfault at 0 ip 00007ffddd190ab2 sp 00007ffdba3e15c8 error 4 in libback-ldbm.so[7ffddd15d000+9b000]

I see it also was not able to touch it's log files, did you manipulate with them or the directory they are stored in? It may be related to the crash.

Could you please enable the VM to generate the core for DS so that we can report proper bug to 389-ds-base component? See HOWTO below:

I have reproduced the crash and attached the stacktrace.

Comment 12 Martin Kosek 2014-08-20 10:58:48 UTC

Cool! Re-assigning to DS team so that they can fix the crash. Once that is fixed, Web UI should run smoothly again.

Comment 13 Varun Mylaraiah 2014-08-20 12:20:11 UTC

Thank you Martin.

Comment 15 Ludwig 2014-08-21 12:45:44 UTC

The search filter is (&(objectClass=posixaccount)(!(memberOf=cn=group1,cn=groups,cn=accounts,dc=testrelm,dc=com)))"

and the crash is in idl_is_allids() called with a NULL list. 

Looks like this was fixed as a side effect of ticket #47313 (bz1044133), which was not backported to 1.2.11

Comment 16 Ludwig 2014-08-21 16:07:38 UTC

The code was introduce to 1.2.11.15-30 by another backport for a VLV fix, but the check in idl_is_allids is missing

Comment 17 Sankar Ramalingam 2014-08-21 17:28:39 UTC

Request Varun to mark qe_test_coverage+ flag if its automated in IPA.

git patch file (389-ds-base-1.2.11) -- backporting just the NULL idl checking in idl_common.c from the commit a71633d56951dd6c4d0368c790b85628f1598968

Comment 21 Noriko Hosoi 2014-08-21 20:17:50 UTC

Steps:
The search filter:
(&(objectClass=posixaccount)(!(memberOf=cn=group1,cn=groups,cn=accounts,dc=testrelm,dc=com)))

Entries that satisfy "objectClass=posixaccount" need to exist, while
entries that satisfy "memberOf=cn=group1,cn=groups,cn=accounts,dc=testrelm,dc=com" should not exist.

If the search does not crash the server, the fix is verified.

Comment 22 Noriko Hosoi 2014-08-21 23:05:22 UTC

Thanks to Nathan for reviewing the patch.

Pusehd to 389-ds-base-1.2.11:

Comment 24 Varun Mylaraiah 2014-08-22 09:41:03 UTC

I have upgraded my setup to latest 389-ds-base-1.2.11.15-42.el6.
And I tested manually by adding 10 users,100 users and more than 10 netgroups in IPA-WebUI, no crash observed. Hence marking bug as verified.

tested ipa-server version :: ipa-server-3.0.0-42.el6.x86_64
