Oliver added the following code to enable domains:

add the following to "/var/snap/microstack/common/etc/horizon/local_settings.d/_05_snap_tweaks.py" to enable domains:

# Setup multidomain support
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"

Additions seen added to _05_snap_tweaks.py:

Then ran:

sudo snap restart microstack.horizon-uwsgi
