This crash was also seen in 7.3
Do you have a reasonable reproducer?
Abrt report is not enough.
Please provide reasonable steps to reproduce.
Steeve was so kind to provide me access to one of his test system showing this issue. I think this issues was exposed by https://bugzilla.redhat.com/show_bug.cgi?id=1438374. The backend crashes, the frontend has to setup a new connection which might take some time especially if the backend crashes agan during this time. If then SSSD is shut down the hash might already contain a connection object, although not properly initialized, to avoid multiple initializations.
I prepared a test build with the NULL check before calling dbus_connection_unregister_object_path() and hope that Steeve can confirm that it fixes the issue.
Marking the bug as VERIFIED.
Tested using ipa-server-4.5.0-13.el7.x86_64 on RHEL7.4
