Once again I venture into the lands of poorly documented keystoneauth1 calls. This time, I want to be able to validate if a stored keystone authentication token is valid. Here's the best I could come up with, I'd be interested in others have something better. For this to work, we need a service account to create a keystone client with, and then we can ask that client questions about random other tokens... from keystoneauth1 import exceptions from keystoneauth1.identity import v3 from keystoneauth1 import session from keystoneclient.v3 import client def validate_keystone_token(service_auth, token): """Validate a keystone token. Returns True if the token is valid, False otherwise. """ # We need a keystone client as the service service_session = session.Session(auth=service_auth) service_keystone = client.Client(session=service_session) try: user = service_keystone.tokens.validate(token) except exceptions.http.NotFound: return False # Require that there be an access group with our configured name group = None for g in service_keystone.groups.list(): if g.name == 'mygroup': group = g if not group: return False # Require that the user be in that group try: service_keystone.users.check_in_group(user.user_id, group.id) except exceptions.http.NotFound: return False return True # Authenticate the service user service_auth = v3.Password( auth_url='http://kolla.home.stillhq.com:5000', username='admin', password='...', project_name='admin', user_domain_id='default', project_domain_id='default') # Create a token we can test user_auth =…
