If you cannot login to Rogo try enabling authentication debugging via the display_auth_debug setting in config/config.inc.php
$display_auth_debug = true;
This will add extra information to the login page:
If you view the source of the page if will be displayed in a more readable format:

If no login attempt has been made it will show you only which plugins managed it managed to find in Rogo. You should check that all that you expect are listed, and that they are in the order you expect.
If there are any failures at this stage it means that the $authentication setting in the config/config.inc.php is incorrect.
If that is the case try logging in.
