Hi guys,

Finally I figured out the problem of dashboad sign in failure. After an
upgrade of openstack packages, I must have changed the config in my
nova.conf accidentally. In order to be able to sign in on dashboard,
enabled_apis must at least have osapi_compute. In my case, this variable
was set to metadata only. I fixed the issue by setting enabled_apis to
ec2,osapi_compute,metadata.

I would be glad if this could help anybody.

Amine.
