При интеграции drupal 6 и smfforum 1.9 (Друпал - новая система, форум - существует несколько лет) возникли сложности: Не проходит тест на аутентификацию системы:
You are not authenticated in SMF now. Please login to SMF and test again. You may refresh settings!

В readme написано:
If you see message "You are not authenticated in SMF now." beenig logged in SMF and Drupal as admin, it is probably mean your settings are wrong.
You should go to SMF settings and revise Server and qookie settings or do something else in your environment, site and forum layout and settings.

Какие именно настройки нужно изменить?

Спасибо!
