Description of problem:
I have workstations configured to find their automount maps via sssd on a FreeIPA installation (configured using ipa-client-automount).

* If I clean out the sssd cache and reboot (I discovered this after changing the keytab on a machine), the autofs maps aren't found.

* If I restart autofs, it picks up the mounts and things work. This could indicate it's a network timing issue.

* On subsequent boots the maps are there, presumably because sssd has cached them.

Version-Release number of selected component (if applicable):
sssd-1.16.1-1.fc27.x86_64
autofs-5.1.4-6.fc27.x86_64

How reproducible:
Consistently

Steps to Reproduce:
1. systemctl stop sssd
2. rm /var/lib/sss/db/*
3. systemctl reboot

Actual results:
autofs-managed mount points empty

Expected results:
autofs-managed mount points found and activated properly.
