Comment 1 Jakub Hrozek 2018-12-03 09:03:19 UTC

Thank you for the bug report, do you know how to reproduce this bug? Or were there any logs?

Comment 2 Madhuri 2018-12-03 09:11:33 UTC

Hello Jakub,

You can reproduce this bug by cloning the beaker job client/ldap_provider/case_sensitive
https://beaker.engineering.redhat.com/jobs/3190937

And log for above beaker job,
http://beaker-archive.host.prod.eng.bos.redhat.com/beaker-logs/2018/12/31909/3190937/6241900/85127061/taskout.log

Thank you, I cloned the test job and can reproduce the problem as well.

Comment 4 Lukas Slebodnik 2018-12-03 16:14:12 UTC

I assume crash is caused by forgotten TODO

https://pagure.io/SSSD/sssd/blob/6f113c7ddeaa5c82558e10118b499d22bf7a2b/f/src/providers/proxy/proxy_auth.c#_586

It's worse, the current version doesn't even get to this point, the proxy_child crashes even before because its D-Bus name is not compliant. It's tracked with a PR, at least. The todo is then the next thing that needs to be fixed..

Comment 10 Michal Zidek 2018-12-11 20:05:23 UTC

I realized this is not QE acked so, I am moving this back to POST.

Steven, can you please QE ack this? The patches are ready (I even did a scratch build and wanted to push to OSCI when I hit the missing ack).

Comment 12 Madhuri 2019-01-16 06:29:07 UTC

Verified with:
sssd-2.0.0-38.el8.x86_64

Successful beaker without any crash,

case sensitive with openldap:
https://beaker.engineering.redhat.com/jobs/3287572

case sensitive with 389 ds:
https://beaker.engineering.redhat.com/jobs/3287573

From the above marking this bug as Verified.
