Hi everyone i have a problem with keystone, I am istalling openstack following this tutorial https://github.com/ChaimaGhribi/OpenStack-Icehouse-Installation/blob/master/OpenStack-Icehouse-Installation.rst (https://github.com/ChaimaGhribi/OpenS...) when i enset the environment variables OS_SERVICE_TOKEN and OS_SERVICE_ENDPOINT and load the credential file admin_creds, then when i started the command keystone user-list or keystone token-get i got the error :

Authorization Failed: An unexpected error prevented the server from fulfilling your request. (HTTP 500)

here the configuration i have: in /etc/keystone/keystone.conf

[database]
connection = mysql://keystone:KEYSTONE_DBPASS@localhost/keystone

[DEFAULT]
admin_token=ADMIN
log_dir=/var/log/keystone

when i set the environment variables to 

OS_SERVICE_TOKEN=ADMIN
OS_SERVICE_ENDPOINT=http://controller:35357/v2.0

everything work but when i unset these variables and load the file

export OS_USERNAME=admin
export OS_PASSWORD=admin_pass
export OS_TENANT_NAME=admin
export OS_AUTH_URL=http://controller:35357/v2.0

then that error appears, can anyone help to know what is my problem ? here is the output of keystone debug

I had single quotes around mariadb password in keystone.conf mysql connection uri

Changed it from

[database] ... connection = mysql://keystone:'KEYSTONE_DBPASS'@controller/keystone

To..

[database] ... connection = mysql://keystone:KEYSTONE_DBPASS@controller/keystone

and viola!

This line:

2015-03-31 09:02:57.681 4874 TRACE root error: [Errno 98] Address already in use

...suggests that Keystone's not starting because it's already running. Make sure the old Keystone's fully stopped before starting the new one.

$ ps aux |grep -i keystone

...will tell you if it's currently running or not.

i stopped the service and started to run again without any environment variables, it returns a connection problem

[root@controller etc]# keystone --os-username admin --os-password adminp --os-auth-url http://localhost:35357/v2.0 token-get Authorization Failed: Unable to establish connection to http://localhost:35357/v2.0/tokens

when i reply the commend with debug option, it retuns this: [root@controller etc]# keystone --os-username admin --os-password adminp --os-auth-url http://localhost:35357/v2.0 --debug token-get DEBUG:keystoneclient.session:REQ: curl -i -X POST http://localhost:35357/v2.0/tokens -H "Content-Type: application/json" -H "Accept: application/json" -H "User-Agent: python-keystoneclient" -d '{"auth": {"passwordCredentials": {"username": "admin", "password": "adminp"}}}' INFO:requests.packages.urllib3.connectionpool:Starting new HTTP connection (1): localhost Authorization Failed: Unable to establish connection to http://localhost:35357/v2.0/tokens

and nothing is added in the log file after running these commands.

Hi your adminrc file shows that your password is admin_pass . Try with that password.

keystone --os-username admin --os-password admin_pass --os-auth-url http://localhost:35357/v2.0 token-get
