Select one of the following login mechanisms for your cluster.
# If all users will authenticate with Google, "configure Google login":#google.
+# If all users will authenticate with an OpenID Connect provider (other than Google), "configure OpenID Connect":#oidc.
# If all users will authenticate with an existing LDAP service, "configure LDAP":#ldap.
# If all users will authenticate using PAM as configured on your controller node, "configure PAM":#pam.
# Add the Redirect URI: @https://ClusterID.example.com/login@
# Copy the values of *Client ID* and *Client secret* to the @Login.Google@ section of @config.yml@.
-<pre>
+{% codeblock as yaml %}
Login:
Google:
Enable: true
ClientID: "0000000000000-zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz.apps.googleusercontent.com"
ClientSecret: "zzzzzzzzzzzzzzzzzzzzzzzz"
-</pre>
+{% endcodeblock %}
+
+h2(#oidc). OpenID Connect
+
+With this configuration, users will sign in with a third-party OpenID Connect provider such as GitHub, Auth0, Okta, or PingFederate.
+
+Similar to the Google login section above, you will need to register your Arvados cluster with the provider as an application (relying party). When asked for a redirect URL or callback URL, use @https://ClusterID.example.com/login@ (the external URL of your controller service, plus @/login@).
+
+The provider will supply an issuer URL, client ID, and client secret. Add these to your Arvados configuration.
+
+{% codeblock as yaml %}
+ Login:
+ OpenIDConnect:
+ Enable: true
+ Issuer: https://accounts.example.com/
+ ClientID: "0123456789abcdef"
+ ClientSecret: "zzzzzzzzzzzzzzzzzzzzzzzz"
+{% endcodeblock %}
+
+h3. Accepting OpenID bearer tokens as Arvados API tokens
+
+Arvados can also be configured to accept provider-issued access tokens as Arvados API tokens by setting @Login.OpenIDConnect.AcceptAccessToken@ to @true@. This can be useful for integrating third party applications.
+
+{% codeblock as yaml %}
+ Login:
+ OpenIDConnect:
+ AcceptAccessToken: true
+ AcceptAccessTokenScope: "arvados"
+{% endcodeblock %}
+
+# If the provider-issued tokens are JWTs, and @Login.OpenIDConnect.AcceptAccessTokenScope@ is not empty, Arvados will check that the token contains the configured scope, and reject tokens that do not have the configured scope. This can be used to control which users or applications are permitted to access your Arvados instance.
+# Tokens are validated by presenting them to the UserInfo endpoint advertised by the OIDC provider.
+# Once validated, a token is cached and accepted without re-checking for up to 10 minutes.
+# A token that fails validation is cached and will not be re-checked for up to 5 minutes.
+# Network errors and HTTP 5xx responses from the provider's UserInfo endpoint are not cached.
+# The OIDC token cache size is currently limited to 1000 tokens, if the number of distinct tokens used in a 5 minute period is greater than this, tokens may be checked more frequently.
+
+Check the OpenIDConnect section in the "default config file":{{site.baseurl}}/admin/config.html for more details and configuration options.
h2(#ldap). LDAP
Enable LDAP authentication and provide your LDAP server's host, port, and credentials (if needed to search the directory) in @config.yml@:
-<pre>
+{% codeblock as yaml %}
Login:
LDAP:
Enable: true
SearchBindUser: cn=lookupuser,dc=example,dc=com
SearchBindPassword: xxxxxxxx
SearchBase: ou=Users,dc=example,dc=com
-</pre>
+{% endcodeblock %}
The email address reported by LDAP will be used as primary key for Arvados accounts. This means *users must not be able to edit their own email addresses* in the directory.
Check the LDAP section in the "default config file":{{site.baseurl}}/admin/config.html for more details and configuration options.
-h2(#pam). PAM (experimental)
+h2(#pam). PAM
With this configuration, authentication is done according to the Linux PAM ("Pluggable Authentication Modules") configuration on your controller host.
Enable PAM authentication in @config.yml@:
-<pre>
+{% codeblock as yaml %}
Login:
PAM:
Enable: true
-</pre>
+{% endcodeblock %}
Check the "default config file":{{site.baseurl}}/admin/config.html for more PAM configuration options.
-The default PAM configuration on most Linux systems uses the local password database in @/etc/shadow@ for all logins. In this case, in order to log in to Arvados, users must have a shell account and password on the controller host itself. This can be convenient for a single-user or test cluster.
+The default PAM configuration on most Linux systems uses the local user/password database in @/etc/passwd@ and @/etc/shadow@ for all logins. In this case, in order to log in to Arvados, users must have a UNIX account and password on the controller host itself. This can be convenient for a single-user or test cluster. Configuring a user account with a shell of @/bin/false@ will enable the user to log into Arvados but not log into shell login on the controller host.
-PAM can also be configured to use different backends like LDAP. In a production environment, PAM configuration should use the service name ("arvados" by default) to set a separate policy for Arvados logins: generally, Arvados users should not have shell accounts on the controller node.
+PAM can also be configured to use other authentication systems such such as NIS or Kerberos. In a production environment, PAM configuration should use the service name ("arvados" by default) and set a separate policy for Arvados login. In this case, Arvados users should not have shell accounts on the controller node.
For information about configuring PAM, refer to the "PAM System Administrator's Guide":http://www.linux-pam.org/Linux-PAM-html/Linux-PAM_SAG.html.
