Similar settings should be added to @clsr2@ & @clsr3@ hosts, so that all clusters in the federation can talk to each other.
-The @ActivateUsers@ setting indicates whether users from a given cluster are automatically activated or they require manual activation. User activation is covered in more detail in the "user activation section":{{site.baseurl}}/admin/activation.html. In the current example, users from @clsr2@ would be automatically, activated, but users from @clsr3@ would require an admin to activate the account.

h2(#LoginCluster). User management
h3. Centralized (LoginCluster) federation
-If all clusters belong to the same organization, and users in that organization should have access to all the clusters, user management can be simplified by setting the @LoginCluster@ which manages the user database used by all other clusters in the federation. To do this, choose one cluster in the federation which will be the 'login cluster'. Set the the @Login.LoginCluster@ configuration value on all clusters in the federation to the cluster id of the login cluster. After setting @LoginCluster@, restart arvados-api-server and arvados-controller.

-The @LoginCluster@ configuration redirects all user logins to the LoginCluster, and the LoginCluster will issue API tokens which will be accepted by the federation. Users are activated or deactivated across the entire federation based on their status on the master cluster.

-Note: tokens issued by the master cluster need to be periodically re-validated when used on other clusters in the federation. The period between revalidation attempts is configured with @Login.RemoteTokenRefresh@. The default is 5 minutes. A longer period reduces overhead from validating tokens, but means it may take longer for other clusters to notice when a token has been revoked or a user has changed status (being activated/deactivated, admin flag changed).

h2. Testing
Following the above example, let's suppose @clsr1@ is our "home cluster", that is to say, we use our @clsr1@ user account as our federated identity and both @clsr2@ and @clsr3@ remote clusters are set up to allow users from @clsr1@ and to auto-activate them. The first thing to do would be to log into a remote workbench using the local user token. This can be done following these steps:
1. Log into the local workbench and get the user token
-2. Visit the remote workbench specifying the local user token by URL: @https://workbench.cluster2.com?api_token=token_from_clsr1@
+2. Visit the remote workbench specifying the local user token by URL: @https://workbench.cluster2.example?api_token=token_from_clsr1@
3. You should now be logged into @clsr2@ with your account from @clsr1@
To further test the federation setup, you can create a collection on @clsr2@, uploading some files and copying its UUID. Next, logged into a shell node on your home cluster you should be able to get that collection by running:
projects / arvados.git / blobdiff
