oauthenticator.globus

oauthenticator.globus#

A JupyterHub authenticator class for use with Globus as an identity provider.

class oauthenticator.globus.GlobusOAuthenticator(**kwargs: Any)#

The Globus OAuthenticator handles authentication, authorization, and sets transfer tokens on the spawner environment variables via a pre_spawn_start hook.

admin_globus_groups c.GlobusOAuthenticator.admin_globus_groups = Set()#

Allow members of selected Globus groups to sign in and consider them as JupyterHub admins. Globus groups should be specified using their UUIDs.

If this is set and a user isn’t part of one of these groups or listed in admin_users, a user signing in will have their admin status revoked.

If this is configured, the default value of the scope configuration is appended with the scope urn:globus:auth:scope:groups.api.globus.org:view_my_groups_and_memberships.

admin_users c.GlobusOAuthenticator.admin_users = Set()#

Set of users that will have admin rights on this JupyterHub.

Note: As of JupyterHub 2.0, full admin rights should not be required, and more precise permissions can be managed via roles.

Admin users have extra privileges:

Use the admin panel to see list of users logged in
Add / remove users in some authenticators
Restart / halt the hub
Start / stop users’ single-user servers
Can access each individual users’ single-user server (if configured)

Admin access should be treated the same way root access is.

Defaults to an empty set, in which case no user has admin access.

allow_all c.GlobusOAuthenticator.allow_all = Bool(False)#: Allow all authenticated users to login.

New in version 16.0.

allow_existing_users c.GlobusOAuthenticator.allow_existing_users = Bool(False)#

Allow existing users to login.

An existing user is a user in JupyterHub’s database of users, and it includes all users that has previously logged in.

Warning

Before enabling this you should review the existing users in the JupyterHub admin panel at /hub/admin. You may find users existing there because they have once been declared in config such as allowed_users or once been allowed to sign in.

Warning

When this is enabled and you are to remove access for one or more users allowed via other config options, you must make sure that they are not part of the database of users still. This can be tricky to do if you stop allowing a group of externally managed users for example.

With this enabled, JupyterHub admin users can visit /hub/admin or use JupyterHub’s REST API to add and remove users as a way to allow them access.

The username for existing users must match the normalized username returned by the authenticator. When creating users, only lowercase letters should be used unless MWOAuthenticator is used.

Note

Allowing existing users is done by adding existing users on startup and newly created users to the allowed_users set. Due to that, you can’t rely on this config to independently allow existing users if you for example would reset allowed_users after startup.

New in version 16.0.

Changed in version 16.0: Before this config was available, the default behavior was to allow existing users if allowed_users was configured with one or more user.

allowed_globus_groups c.GlobusOAuthenticator.allowed_globus_groups = Set()#

Allow members of selected Globus groups to sign in. Globus groups should be specified using their UUIDs.

If this is configured, the default value of the scope configuration is appended with the scope urn:globus:auth:scope:groups.api.globus.org:view_my_groups_and_memberships.

allowed_users c.GlobusOAuthenticator.allowed_users = Set()#

Set of usernames that are allowed to log in.

Use this with supported authenticators to restrict which users can log in. This is an additional list that further restricts users, beyond whatever restrictions the authenticator has in place. Any user in this list is granted the ‘user’ role on hub startup.

If empty, does not perform any additional restriction.

Changed in version 1.2: Authenticator.whitelist renamed to allowed_users

auth_refresh_age c.GlobusOAuthenticator.auth_refresh_age = Int(300)#

The max age (in seconds) of authentication info before forcing a refresh of user auth info.

Refreshing auth info allows, e.g. requesting/re-validating auth tokens.

See refresh_user() for what happens when user auth info is refreshed (nothing by default).

authorize_url c.GlobusOAuthenticator.authorize_url = Unicode('')#

The URL to where the user is to be redirected initially based on the OAuth2 protocol. The user will be redirected back with an authorization grant code after authenticating successfully with the identity provider.

For more context, see the Protocol Flow section in the OAuth2 standard document, specifically steps A-B.

auto_login c.GlobusOAuthenticator.auto_login = Bool(False)#

Automatically begin the login process

rather than starting with a “Login with…” link at /hub/login

To work, .login_url() must give a URL other than the default /hub/login, such as an oauth handler or another automatic login handler, registered with .get_handlers().

New in version 0.8.

auto_login_oauth2_authorize c.GlobusOAuthenticator.auto_login_oauth2_authorize = Bool(False)#

Automatically begin login process for OAuth2 authorization requests

When another application is using JupyterHub as OAuth2 provider, it sends users to /hub/api/oauth2/authorize. If the user isn’t logged in already, and auto_login is not set, the user will be dumped on the hub’s home page, without any context on what to do next.

Setting this to true will automatically redirect users to login if they aren’t logged in only on the /hub/api/oauth2/authorize endpoint.

New in version 1.5.

basic_auth c.GlobusOAuthenticator.basic_auth = Bool(False)#

Whether or to use HTTP Basic authentication instead of form based authentication in requests to token_url.

When using HTTP Basic authentication, a HTTP header is set with the client_id and client_secret encoded in it.

When using form based authentication, the client_id and client_secret is put in the HTTP POST request’s body.

Changed in version 16.0.0: This configuration now toggles between HTTP Basic authentication and form based authentication when working against the token_url.

Previously when this was configured True, both would be used contrary to a recommendation in OAuth 2.0 documentation.

Changed in version 16.0.2: The default value for this configuration for GenericOAuthenticator changed from True to False.

blocked_users c.GlobusOAuthenticator.blocked_users = Set()#

Set of usernames that are not allowed to log in.

Use this with supported authenticators to restrict which users can not log in. This is an additional block list that further restricts users, beyond whatever restrictions the authenticator has in place.

If empty, does not perform any additional restriction.

Changed in version 1.2: Authenticator.blacklist renamed to blocked_users

build_auth_state_dict(token_info, user_info)#: Usernames (and therefore Jupyterhub accounts) will correspond to a Globus User ID, so foouser@globusid.org will have the ‘foouser’ account in Jupyterhub.

async check_allowed(username, auth_model)#: Overrides the OAuthenticator.check_allowed to also allow users part of allowed_globus_groups.

client_id c.GlobusOAuthenticator.client_id = Unicode('')#: The client id of the OAuth2 application registered with the identity provider.

client_secret c.GlobusOAuthenticator.client_secret = Unicode('')#: The client secret of the OAuth2 application registered with the identity provider.

custom_403_message c.GlobusOAuthenticator.custom_403_message = Unicode('Sorry, you are not currently authorized to use this hub. Please contact the hub administrator.')#: The message to be shown when user was not allowed

delete_invalid_users c.GlobusOAuthenticator.delete_invalid_users = Bool(False)#

Delete any users from the database that do not pass validation

When JupyterHub starts, .add_user will be called on each user in the database to verify that all users are still valid.

If delete_invalid_users is True, any users that do not pass validation will be deleted from the database. Use this if users might be deleted from an external system, such as local user accounts.

If False (default), invalid users remain in the Hub’s database and a warning will be issued. This is the default to avoid data loss due to config changes.

enable_auth_state c.GlobusOAuthenticator.enable_auth_state = Bool(False)#

Enable persisting auth_state (if available).

auth_state will be encrypted and stored in the Hub’s database. This can include things like authentication tokens, etc. to be passed to Spawners as environment variables.

Encrypting auth_state requires the cryptography package.

Additionally, the JUPYTERHUB_CRYPT_KEY environment variable must contain one (or more, separated by ;) 32B encryption keys. These can be either base64 or hex-encoded.

If encryption is unavailable, auth_state cannot be persisted.

New in JupyterHub 0.8

exclude_tokens c.GlobusOAuthenticator.exclude_tokens = List()#: Exclude tokens from being passed into user environments when they start notebooks, Terminals, etc.

extra_authorize_params c.GlobusOAuthenticator.extra_authorize_params = Dict()#: Extra GET params to send along with the initial OAuth request to the OAuth provider.

globus_groups_url c.GlobusOAuthenticator.globus_groups_url = Unicode('https://groups.api.globus.org/v2/groups/my_groups')#: Globus URL to get list of user’s Groups.

globus_local_endpoint c.GlobusOAuthenticator.globus_local_endpoint = Unicode('')#: If JupyterHub is also a Globus endpoint, its endpoint id can be specified here.

http_request_kwargs c.GlobusOAuthenticator.http_request_kwargs = Dict()#

Extra default kwargs passed to all HTTPRequests.

# Example: send requests through a proxy
c.OAuthenticator.http_request_kwargs = {
    "proxy_host": "proxy.example.com",
    "proxy_port": 8080,
}

# Example: validate against certain root certificates
c.OAuthenticator.http_request_kwargs = {
    "ca_certs": "/path/to/a.crt",
}

See tornado.httpclient.HTTPRequest for all kwargs options you can pass. Note that the HTTP client making these requests is tornado.httpclient.AsyncHTTPClient.

identity_provider c.GlobusOAuthenticator.identity_provider = Unicode('')#

Restrict which institution (domain) a user can use to login (GlobusID, University of Hogwarts, etc.). This should be set in the app at developers.globus.org, but this acts as an additional check to prevent unnecessary account creation.

Note that users with an associated email domains must still be allowed via another config, such as allow_all.

login_service c.GlobusOAuthenticator.login_service = Unicode('OAuth 2.0')#

Name of the login service or identity provider that this authenticator is using to authenticate users.

This config influences the text on a button shown to unauthenticated users before they click it to login, assuming auto_login isn’t configured True.

The login button’s text will be “Login with <login_service>”.

logout_handler#: alias of GlobusLogoutHandler

logout_redirect_url c.GlobusOAuthenticator.logout_redirect_url = Unicode('')#: When configured, users are not presented with the JupyterHub logout page, but instead redirected to this destination.

manage_groups c.GlobusOAuthenticator.manage_groups = Bool(False)#

Let authenticator manage user groups

If True, Authenticator.authenticate and/or .refresh_user may return a list of group names in the ‘groups’ field, which will be assigned to the user.

All group-assignment APIs are disabled if this is True.

oauth_callback_url c.GlobusOAuthenticator.oauth_callback_url = Unicode('')#

Callback URL to use.

When registering an OAuth2 application with an identity provider, this is typically called the redirect url.

Should very likely be set to https://[your-domain]/hub/oauth_callback.

post_auth_hook c.GlobusOAuthenticator.post_auth_hook = Any(None)#

An optional hook function that you can implement to do some bootstrapping work during authentication. For example, loading user account details from an external system.

This function is called after the user has passed all authentication checks and is ready to successfully authenticate. This function must return the authentication dict reguardless of changes to it.

This maybe a coroutine.

Example:

import os, pwd
def my_hook(authenticator, handler, authentication):
    user_data = pwd.getpwnam(authentication['name'])
    spawn_data = {
        'pw_data': user_data
        'gid_list': os.getgrouplist(authentication['name'], user_data.pw_gid)
    }

    if authentication['auth_state'] is None:
        authentication['auth_state'] = {}
    authentication['auth_state']['spawn_data'] = spawn_data

    return authentication

c.Authenticator.post_auth_hook = my_hook

async pre_spawn_start(user, spawner)#: Add tokens to the spawner whenever the spawner starts a notebook. This will allow users to create a transfer client: globus-sdk-python.readthedocs.io/en/stable/tutorial/#tutorial-step4

refresh_pre_spawn c.GlobusOAuthenticator.refresh_pre_spawn = Bool(False)#

Force refresh of auth prior to spawn.

This forces refresh_user() to be called prior to launching a server, to ensure that auth state is up-to-date.

This can be important when e.g. auth tokens that may have expired are passed to the spawner via environment variables from auth_state.

If refresh_user cannot refresh the user auth data, launch will fail until the user logs in again.

revocation_url c.GlobusOAuthenticator.revocation_url = Unicode('https://auth.globus.org/v2/oauth2/token/revoke')#: Globus URL to revoke live tokens.

async revoke_service_tokens(services)#

Revoke live Globus access and refresh tokens.

Revoking inert or non-existent tokens does nothing. Services are defined by dicts returned by tokens.by_resource_server.

For example:

services = {
    'transfer.api.globus.org': {'access_token': 'token'},
    <Additional services>...
}

revoke_tokens_on_logout c.GlobusOAuthenticator.revoke_tokens_on_logout = Bool(False)#: Revoke tokens so they cannot be used again. Single-user servers MUST be restarted after logout in order to get a fresh working set of tokens.

scope c.GlobusOAuthenticator.scope = List()#

The OAuth scopes to request.

See the OAuth documentation of your OAuth provider for options.

token_params c.GlobusOAuthenticator.token_params = Dict()#: Extra parameters for first POST request exchanging the OAuth code for an Access Token

token_url c.GlobusOAuthenticator.token_url = Unicode('')#

The URL to where this authenticator makes a request to acquire an access token based on the authorization code received by the user returning from the authorize_url.

For more context, see the Protocol Flow section in the OAuth2 standard document, specifically steps C-D.

async update_auth_model(auth_model)#

Fetch and store globus_groups in auth state if allowed_globus_groups or admin_globus_groups is configured.

Sets admin status to True or False if admin_globus_groups is configured and the user isn’t part of admin_users. Note that leaving it at None makes users able to retain an admin status while setting it to False makes it be revoked.

user_info_to_username(user_info)#: Usernames (and therefore Jupyterhub accounts) will correspond to a Globus User ID, so foouser@globusid.org will have the ‘foouser’ account in Jupyterhub.

userdata_params c.GlobusOAuthenticator.userdata_params = Dict()#: Userdata params to get user data login information.

userdata_token_method c.GlobusOAuthenticator.userdata_token_method = Unicode('header')#

Method for sending access token in userdata request.

Supported methods: header, url.

userdata_url c.GlobusOAuthenticator.userdata_url = Unicode('')#

The URL to where this authenticator makes a request to acquire user details with an access token received via a request to the token_url.

For more context, see the Protocol Flow section in the OAuth2 standard document, specifically steps E-F.

username_claim c.GlobusOAuthenticator.username_claim = Unicode('username')#

The key to get the JupyterHub username from in the data response to the request made to userdata_url.

Examples include: email, username, nickname

What keys are available will depend on the scopes requested and the authenticator used.

username_from_email c.GlobusOAuthenticator.username_from_email = Bool(False)#: Create username from email address, not preferred username. If an identity provider is specified, email address must be from the same domain. Email scope will be set automatically.

username_map c.GlobusOAuthenticator.username_map = Dict()#

Dictionary mapping authenticator usernames to JupyterHub users.

Primarily used to normalize OAuth user names to local users.

username_pattern c.GlobusOAuthenticator.username_pattern = Unicode('')#

Regular expression pattern that all valid usernames must match.

If a username does not match the pattern specified here, authentication will not be attempted.

If not set, allow any username.

validate_server_cert c.GlobusOAuthenticator.validate_server_cert = Bool(False)#

Determines if certificates are validated.

Only set this to False if you feel confident it will not be a security concern.

whitelist c.GlobusOAuthenticator.whitelist = Set()#: Deprecated, use Authenticator.allowed_users

class oauthenticator.globus.LocalGlobusOAuthenticator(**kwargs: Any)#

A version that mixes in local system user creation

add_user_cmd c.LocalGlobusOAuthenticator.add_user_cmd = Command()#

The command to use for creating users as a list of strings

For each element in the list, the string USERNAME will be replaced with the user’s username. The username will also be appended as the final argument.

For Linux, the default value is:

[‘adduser’, ‘-q’, ‘–gecos’, ‘””’, ‘–disabled-password’]

To specify a custom home directory, set this to:

[‘adduser’, ‘-q’, ‘–gecos’, ‘””’, ‘–home’, ‘/customhome/USERNAME’, ‘–disabled-password’]

This will run the command:

adduser -q –gecos “” –home /customhome/river –disabled-password river

when the user ‘river’ is created.

admin_globus_groups c.LocalGlobusOAuthenticator.admin_globus_groups = Set()#

Allow members of selected Globus groups to sign in and consider them as JupyterHub admins. Globus groups should be specified using their UUIDs.

If this is set and a user isn’t part of one of these groups or listed in admin_users, a user signing in will have their admin status revoked.
