Hi Aaron, I found this information very helpful for debugging a CentOS 7 box that is
having the same problem, thank you.
On my box, sudo over SSSD is working, but not with host groups, only with specific hosts
listed. So there's some problem with the host expansion as you point out, but I'm
unable to find the right log entries. I used the document at
to set up the logging.
Do you know any keywords that I can grep for that would narrow down the log lines that are
relevant? These log files are really big!
