Drupal with integrated phpBB

Hi

I have been asked about the possibility of integrating a phpBB forum into a Drupal site (believe me, there are very good, if complicated reasons for doing this). I know quite a lot about phpBB, and nothing about Drupal, although I do know that it is possible to do this.

The most pressing question I need answering is about permissions. Will it be possible to set different permissions within the phpBB forum to those within the Drupal site, and to define the phpBB permissions from within the phpBB forum?

ie, if a person is an administrator on the main Drupal site, will it be possible to have them as just a normal member in the forum, and vice versa, and will the Drupal administrators be able to alter the permissions on the forum from outside it?

Thanks for your help.
