According to /var/log/mesages, the main process /usr/sbin/sssd crashed, which is really bad.

It can be uninitialized variable or use after free. Thread 1 (LWP 649): #0 dbus_watch_handle (watch=0xa0, flags=flags@entry=2) at dbus-watch.c:683 __FUNCTION__ = "dbus_watch_handle" Could you put "debug_level = 9" into sssd section and provide log files from directory /var/log/sssd? You can also try to upgrade into sssd-1.12.1-2.fc21, which is in updates-testing.
The necessary information were not provided in last year :-) I believe this is the same case as in upstream ticket https://fedorahosted.org/sssd/ticket/2525. And it is already fixed in 1.12.4 and fedora 21 already contains sssd-1.12.5-3.fc21.

It might be indirectly proved by abrt report linked with this ticket. https://retrace.fedoraproject.org/faf/reports/349418/ It only crashed with older version of sssd. sssd-common 5 0:1.11.4-1.fc20 3 0:1.12.0-7.fc21 1 0:1.11.7-2.fc20 1
For the record, it seems the reason of this ticket was the same as bz 1767159
