As an administrator, I would like to be able to see which users haven't logged in in the past X months.
Currently you'd have to perform the following query on the database:
SELECT a.user_name, from_unixtime(b.attribute_value/1000)
FROM cwd_user a, cwd_user_attribute b
WHERE a.id = b.user_id and b.attribute_name = 'lastAuthenticated'
AND from_unixtime(b.attribute_value/1000) between '2013-11-05 00:00:00' and CURRENT_DATE();
That would be good if you could also see the details for each user on the screen just like you can do in JIRA:
