Hi everyone, I have deployed a new test environment using packstack, everything seems to be working well, except that the keystone service is not loaded and if i enable it, then fails.
I have checked if keystone is really working and it does, i can create a user from CLI and the user is created in the database.
The openstack versions i'm using and the keystone packages installed are:

openstack --version = openstack 1.0.1
packstack --version = packstack Juno 2014.2.dev1468.gd049ea9
CentOS version = CentOS Linux release 7.1.1503 (Core) 

Keystone packages:

python-keystoneclient-0.11.1-1.el7.centos.noarch
python-keystone-2014.2.2-1.el7.noarch
openstack-keystone-2014.2.2-1.el7.noarch
python-keystonemiddleware-1.2.0-1.el7.centos.noarch

The repo im using:

[openstack-juno]
name=OpenStack Juno Repository
baseurl=http://repos.fedorapeople.org/repos/openstack/openstack-juno/epel-7/
enabled=1
skip_if_unavailable=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-RDO-Juno

I have validated this error trying other installations and still facing this issue.

The status of the keystone service in a fresh openstack allinone installation:

openstack-keystone.service - OpenStack Identity Service (code-named Keystone)
   Loaded: loaded (/usr/lib/systemd/system/openstack-keystone.service; disabled)
   Active: inactive (dead)
 
When I enable the openstack-keystone and try to start the service, i have the following error and log:

[root@controller ~]# systemctl status -l openstack-keystone.service

Can this be an issue with the keystone packages in the repository?

Thanks in advance
