How do I resolve this authentication error with OpenStack dashboard?

Question

I have successfully created a cloud using MAAS and juju from the documentation : https://help.ubuntu.com/community/UbuntuCloudInfrastructure

Relation between dashboard and keystone successfully created. But I am unable to login from the web interface of dashboard. It gives an error:

Error: An error occurred authenticating. Please try again later.

I know while preparing these servers I used openstack.cfg file which has the password : openstack. But I am unable to login with that password.

Then I tried to ssh keystone machine and here is maybe something useful:

ls /var/lib/keystone/
cache  glance.passwd  keystone.db  keystone.token  s3_ec2_nova.passwd  s3_nova-volume_ec2_nova.passwd

I think this directory Should have a file called : keystone.passwd ?

I thought I can have a look to that file and get the random password by keystone, but that file does not exist.

juju -v status shows that relation exists between dashboard and keystone.

So what do I do now?

Check your SELINUX status, put it in permissive mode. Your error shouldnt appear. You need to investigate the cause by checking /var/log/audit/audit.log

@ I just reproduced this error by setting SELINUX mode as enforcing.

you can check /var/log/messages and /var/log/secure and the logs under /var/log/http for any openstack-related errors.
