Example usage and Identity features

The openstack CLI is used to interact with the Identity service. It is set up to expect commands in the general form of openstack command argument, followed by flag-like keyword arguments to provide additional (often optional) information. For example, the user list and project create commands can be invoked as follows:

# Using token auth env variables
export OS_SERVICE_TOKEN=secrete_token
openstack user list
openstack project create demo --domain default

# Using token auth flags
openstack --os-token secrete --os-endpoint user list
openstack --os-token secrete --os-endpoint project create demo

# Using user + password + project_name env variables
export OS_USERNAME=admin
export OS_PASSWORD=secrete
export OS_PROJECT_NAME=admin
openstack user list
openstack project create demo --domain default

# Using user + password + project-name flags
openstack --os-username admin --os-password secrete --os-project-name admin user list
openstack --os-username admin --os-password secrete --os-project-name admin project create demo


You configure logging externally to the rest of Identity. The name of the file specifying the logging configuration is set using the log_config option in the [DEFAULT] section of the /etc/keystone/keystone.conf file. To route logging through syslog, set use_syslog=true in the [DEFAULT] section.

A sample logging configuration file is available with the project in etc/logging.conf.sample. Like other OpenStack projects, Identity uses the Python logging module, which provides extensive configuration options that let you define the output levels and formats.


Identity provides a user CRUD (Create, Read, Update, and Delete) filter that Administrators can add to the public_api pipeline. The user CRUD filter enables users to use a HTTP PATCH to change their own password. To enable this extension you should define a user_crud_extension filter, insert it after the *_body middleware and before the public_service application in the public_api WSGI pipeline in keystone-paste.ini. For example:

paste.filter_factory = keystone.contrib.user_crud:CrudExtension.factory

pipeline = sizelimit url_normalize request_id build_auth_context token_auth admin_token_auth json_body ec2_extension user_crud_extension public_service

Each user can then change their own password with a HTTP PATCH.

$ curl -X PATCH http://localhost:5000/v2.0/OS-KSCRUD/users/USERID -H "Content-type: application/json"  \
  -H "X_Auth_Token: AUTHTOKENID" -d '{"user": {"password": "ABCD", "original_password": "DCBA"}}'

In addition to changing their password, all current tokens for the user are invalidated.


Only use a KVS back end for tokens when testing.
