Description Stephen Gallagher 2016-05-12 18:06:41 UTC 
Description of problem:
I ran D-Feet (the graphical D-BUS testing tool) and connected to org.freedesktop.sssd.infopipe.

I then attempted to use org.freedesktop.sssd.infopipe.Users.ListByName, passing it my full username (sgallagh) and a numeric value for the limit.

Instead of getting a response back from D-BUS, the sssd_ifp process crashed.

Version-Release number of selected component:
sssd-dbus-1.13.4-2.fc24
