+
+#.  Go to **Users** and click **Edit** in the **Actions** menu of the corresponding table row.

+    or click the pencil icon if the cluster is already on the list.

+#.  Select the **Use Access Control List (ACL)** checkbox and save changes.
+
+#.  Repeat two previous steps for each cluster on which you want to use ACL for this user.

+#.  Click **Update** to save the user account.
+
+If the user doesn't exist yet, you can do the same when creating it.
