Is there a way to see all users, even the disabled ones?
KanBo queries the SharePoint User Profile Service Application for users. If this Service does not deliver this user (i.e. because (s)he is disabled) there is nothing we can do about it. KanBo depends on SharePoint services. By the end of this year we will introduce a new security model, where you can choose whether the users come from SharePoint or directly from AD. But even then we will implement it to filter out disabled users. The disable users in AD was designed by Microsoft to shut down users, who have left the company.
