Ticket was cloned from Red Hat Bugzilla (product Red Hat Enterprise Linux 7): Bug 1711832

(Adding Sumit's investigation)

It is an issue with the files provider which does not expect to ever be offline and hence does not handle the resetOffline request from the monitor.
If the files provider runs with a different provider and the provider goes offline and back online the files provider might get a resetOffline as well and crash as you have seen it because 'ctx->check_if_online_ptask' is NULL and there is no NULL check in be_ptask_disable()..

To reproduce this easily you can start SSSD with the file provider, it can even be the implicit files provider which is started without any SSSD configuration and send SIGUSR2 to the sssd monitor process.

Per thalman, we should check the task parameter in be_ptask_(enable|disable)
