There are two bugs, really. One is that c-ares returns success and empty address list and the other is that the SSSD does not handle that situation well. Stephen patched the empty list check in the SSSD and I'll clone this bugzilla to c-ares, too. We should investigate how could c-ares return an empty list. Stef, was that problem reproducable in your environment or just a one-time fluke?
