openstack-magnum-2.0.1-0.20160324110644.c0c2bdb.el7.centos.src.rpm  seems to to have no idea

about two commits mentioned above , giving me error :-

Run as admin as suggested in http://egonzalez.org/magnum-in-rdo-openstack-liberty-manual-installation-from-source-code/

# magnum bay-create --name demoswarmbay --baymodel demoswarmbaymodel \
           --master-count 1 --node-count 1

Create for bay swarmbay failed: Failed to create trustee %(username) in domain $(domain_id) (HTTP 500)"

Here I follow explanation done in  http://osdir.com/ml/openstack-dev/2016-02/msg02123.html

which is advising to fix an error using keystone V3

Script 1

# 1. create the necessary domain and user:

export OS_TOKEN=bf2585734da14520868414d44dbe72c7

export OS_URL=http://127.0.0.1:5000/v3
export OS_IDENTITY_API_VERSION=3
openstack domain create magnum
openstack user create trustee_domain_admin --password=secret --domain=magnum
openstack role add --user=trustee_domain_admin --domain=magnum admin

Script 2 ( just cloned devstack to current folder to source functions )

# 2. populate configs
source /root/devstack/functions  
export MAGNUM_CONF=/etc/magnum/magnum.conf
iniset $MAGNUM_CONF trust trustee_domain_id $(openstack domain show magnum | awk '/ id /{print $4}')
iniset $MAGNUM_CONF trust trustee_domain_admin_id $(openstack user show trustee_domain_admin | awk '/ id /{print $4}')
iniset $MAGNUM_CONF trust trustee_domain_admin_password secret 

I completed both ( ran with #!/bin/bash -x ).  All done , but having currently running keystone v2.0

it doesn't help. I keep getting same error.

I am not keystone expert, but looks like I need to go through procedure like described here

"Migrate from keystone v2.0 to keystone v3 OpenStack Liberty"

http://egonzalez.org/migrate-from-keystone-v2-0-to-keystone-v3-openstack-liberty/

Thank you.
