When there is an issue in SSSD, please do not file it by cloning a bug from 2011 linking to a closed upstream ticket. It is then really unclear what to work on.

Please open a new bugzilla instead. When opening a bug, it is also a good idea to include log files and configuration. This bug has no information to work with, so I'm just going to close it.

If you can reproduce the issue in-house, please also give us access to the test machines.
