Make sure you have the base URL's same through out the site.
All base URL's and links from SMF to Drupal and from Drupal to SMF have to start (with www) or (without www).
You have to change the values of $boardurl in smf/Settings.php and $base_url in drupal/sites/default/settings.php to have same base URL's.
Set also all links from Drupal to forum or from forum to Drupal with www. or (without www).
After you do this, you go to SMF >> Admin >> Themes and Layout >> Themes and Settings >> click on "Attempt to reset all themes" in the "Reset Theme URLs and Directories" box.
SMF >> Admin >> Theme Settings >> THEMES AND SETTINGS
and set www. also
Theme Settings - SMF Default Theme - Core

This theme's name: SMF Default Theme - Core
This theme's URL:
http://www.mysite.com/smf/Themes/defaultThis theme's images URL:
http://www.mysite.com/smf/Themes/default/imagesThis theme's directory: your absolute site path/smf/Themes/default
In layouts like
www.mysite.com is the website.
www.mysite.com/forum is the forum.
Ensure that these settings were unchecked

The qookie authetication test shows if smfforum.module authenticates you on the forum with the qookie.
The test shows that something wrong with the qookie or your SMF and Drupal domains are different or have layout that smfforum.module not supports.
To pass this qookie authetication test you should:
1) login in SMF with this admin password
2) login in Dupal with this admin password
3) Go to SMFforum settings and see 4 line (or refresh the browser if you are already in there)
See radio buttons. You may choose Test and save settings.
If you see red line that means that something wrong with the qookie and smfforum.module treats you as unauthenticated.
When you log in SMF see in browser qookie like SMFCookie999 (or so)
When you log in Drupal see in browser qookie like SMFCookie999 (or so)
If you see 2 qookies that is not wright. It means that something wrong with the your settings..
You shoud see only one SMF qookie line, that is ok.
You should try to adjust your links, settings or your environment.
