I have an installed Moodle version (latest version) and a phpBB (forum). I want every user, which log in in the Moodle, can also login in the forum (phpBB) with the same credentials (or through a button goes to the forum, while they have logged in once). So, the table of phpBB's users should find all the moodle's users and copy/update/delete them into the table of phpBB. As I can see, there is no plugin to integrate these two software. I should not touch the Moodle database table of users, because there are already registered users.
