keystoneclient.contrib.auth.v3 package¶

Submodules¶

keystoneclient.contrib.auth.v3.oidc module¶

class keystoneclient.contrib.auth.v3.oidc.OidcPassword(auth_url, identity_provider, protocol, username, password, client_id, client_secret, access_token_endpoint, scope='profile', grant_type='password')¶

Bases: keystoneclient.auth.identity.v3.federated.FederatedBaseAuth

Implement authentication plugin for OpenID Connect protocol.

OIDC or OpenID Connect is a protocol for federated authentication.

The OpenID Connect specification can be found at:: http://openid.net/specs/openid-connect-core-1_0.html

classmethod get_options()¶

get_unscoped_auth_ref(session)¶

Authenticate with OpenID Connect and get back claims.

This is a multi-step process. First an access token must be retrieved, to do this, the username and password, the OpenID Connect client ID and secret, and the access token endpoint must be known.

Secondly, we then exchange the access token upon accessing the protected Keystone endpoint (federated auth URL). This will trigger the OpenID Connect Provider to perform a user introspection and retrieve information (specified in the scope) about the user in the form of an OpenID Connect Claim. These claims will be sent to Keystone in the form of environment variables.

Parameters:	session (keystoneclient.session.Session) – a session object to send out HTTP requests.
Returns:	a token data representation
Return type:	keystoneclient.access.AccessInfo

password¶

username¶

keystoneclient.contrib.auth.v3.saml2 module¶

Bases: keystoneclient.contrib.auth.v3.saml2._BaseSAMLPlugin

Authentication plugin for Microsoft ADFS2.0 IdPs.

Parameters:

auth_url (string) – URL of the Identity Service identity_provider (string) – name of the Identity Provider the client will authenticate against. This parameter will be used to build a dynamic URL used to obtain unscoped OpenStack token. identity_provider_url (string) – An Identity Provider URL, where the SAML2 authentication request will be sent. service_provider_endpoint (string) – Endpoint where an assertion is being sent, for instance: https://host.domain/Shibboleth.sso/ADFS username (string) – User’s login password (string) – User’s password

Bases: keystoneclient.contrib.auth.v3.saml2._BaseSAMLPlugin

Implement authentication plugin for SAML2 protocol.

ECP stands for Enhanced Client or Proxy and is a SAML2 extension for federated authentication where a transportation layer consists of HTTP protocol and XML SOAP messages.

Read for more information on ECP.

Reference the SAML2 ECP specification.

Currently only HTTPBasicAuth mechanism is available for the IdP authenication.

Parameters:

auth_url (string) – URL of the Identity Service identity_provider (string) – name of the Identity Provider the client will authenticate against. This parameter will be used to build a dynamic URL used to obtain unscoped OpenStack token. identity_provider_url (string) – An Identity Provider URL, where the SAML2 authn request will be sent. username (string) – User’s login password (string) – User’s password

get_auth_ref(session, **kwargs)¶

Authenticate via SAML2 protocol and retrieve unscoped token.

This is a multi-step process where a client does federated authn receives an unscoped token.

Federated authentication utilizing SAML2 Enhanced Client or Proxy extension. See Saml2UnscopedToken_get_unscoped_token() for more information on that step. Upon successful authentication and assertion mapping an unscoped token is returned and stored within the plugin object for further use.

:param session : a session object to send out HTTP requests. :type session: keystoneclient.session.Session

Returns:	an object with scoped token’s id and unscoped token json included.
Return type:	keystoneclient.access.AccessInfoV3
