Google login With this configuration, users will sign in with their Google accounts. Use the Google Developers Console to create a set of client credentials. # Select or create a project. # Click *+ Enable APIs and Services*. #* Search for *People API* and click *Enable API*. #* Navigate back to the main "APIs & Services" page. # On the sidebar, click *OAuth consent screen*. #* On consent screen settings, enter your identifying details. #* Under *Authorized domains* add your domain (@example.com@). #* Click *Save*. # On the sidebar, click *Credentials*, then click *Create credentials*→*OAuth client ID* # Under *Application type* select *Web application*. # Add the JavaScript origin: @https://ClusterID.example.com/@ # 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@.
    Login:
      Google:
        Enable: true
        ClientID: "0000000000000-zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz.apps.googleusercontent.com"
        ClientSecret: "zzzzzzzzzzzzzzzzzzzzzzzz"
h2(#oidc). OpenID Connect With this configuration, users will sign in with a third-party OpenID Connect provider. The provider will supply appropriate values for the issuer URL, client ID, and client secret config entries.
    Login:
      OpenIDConnect:
        Enable: true
        Issuer: https://accounts.example.com/
        ClientID: "0123456789abcdef"
        ClientSecret: "zzzzzzzzzzzzzzzzzzzzzzzz"
Check the OpenIDConnect section in the "default config file":{{site.baseurl}}/admin/config.html for more details and configuration options. h2(#ldap). LDAP With this configuration, authentication uses an external LDAP service like OpenLDAP or Active Directory. Enable LDAP authentication and provide your LDAP server's host, port, and credentials (if needed to search the directory) in @config.yml@:
    Login:
      LDAP:
        Enable: true
        URL: ldap://ldap.example.com:389
        SearchBindUser: cn=lookupuser,dc=example,dc=com
        SearchBindPassword: xxxxxxxx
        SearchBase: ou=Users,dc=example,dc=com
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. Additional configuration settings are available: * @StartTLS@ is enabled by default. * @StripDomain@ and @AppendDomain@ modify the username entered by the user before searching for it in the directory. * @SearchAttribute@ (default @uid@) is the LDAP attribute used when searching for usernames. * @SearchFilters@ accepts LDAP filter expressions to control which users can log in. Check the LDAP section in the "default config file":{{site.baseurl}}/admin/config.html for more details and configuration options. h2(#pam). PAM (experimental) 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@:
    Login:
      PAM:
        Enable: true
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. 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. 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.
