I found that using the dashboard to create users is tedious because it adds each single user to ntfs permissions, taking an awful long time for a simple task. I rather created a group in AD and add new users to this group.
Dashboard does not allow to use groups, so I decided not to use dashboard, but create my users manually in the AD Users-and-groups console.
Now, my users do not show up in dashboard - can cope with that, but the problem is, these users do not see newly created shares in remote web access. How can I grant them permissions for that? I am sure there must be an AD equivalent to do that!?
