+=begin
+The portal for registrants has to offer an overview of the domains the user is related to directly or through an organisation.
+Personal relation is defined by matching the personal identification code associated with a domain and the one acquired on
+authentication using electronic ID. Association through a business organisation requires a query to business registry.
+
+  * when user logs in the personal identification code is sent to business registry (using XML service)
+  * business registry returns the list of business registry codes the user is a board member of
+  * the list is cached for two days (configurable)
+  * during that time no new queries are made to business registry for that personal identification code
+    and the cached organisation code listing is used
+  * user sees the listing of domains that are associated with him/her directly or through registered organisation
+  * UI of the portal displays the list of organisation codes and names used to fetch additional domains for the user
+    (currently by clicking on a username in top right corner of the screen).
+    Also time and date of the query to the business registry is displayed with the list of organisations.
+  * if the query to the business registry fails for any reason the list of
+    domains associated directly with the user is still displayed with an error message indicating a problem
+    with receiving current list business entities. Outdated list of organisations cannot be used.
