DAP Admin cannot view user's current password.
You may however change user's current password by clicking on the "Change Password" link.
To log in as a user, in a separate browser (where you are not logged in as WP Admin or DAP Admin), go to the following link:
http://YourSite.com/dap/loginAs.php
On that page, you can log in as a regular User, by entering their email id, and DAP Admin email and password.
