sssd-2.4.0 works from command line but fails to start from systemd/sssctl

[smclinden]

I have build sssd-2.4.0 on Ubutu 18.04 and am able to run it from the command line without problem.

If I try to run it from systemd (sysctl) it fails to start but I get no error messages, even with debugging on,

If I try to start it with sssctl domain-list, it creates a file which did not, previously, exist: /var/log/sssd/sssd_ifp.log

The contents of that file are below. I am sure that this is some kind of configuration issue (perhaps with the build) but I'm stumped as to what it is.
