I've created some flamegraphs of sssd_be, hovering your mouse over the elements should show more information.
This is of sssd_be while running "id <domain user>" with the caches completely flushed: http://svgshare.com/i/MJ.svg
This is of sssd_be while running "sudo -l" as a domain user with sudo privileges: http://svgur.com/i/MX.svg
Clearly there are some symbols missing, but I wasn't sure how to resolve this. If someone could point me to the package(s) needed to fix this, I'd be happy to rerun them.
