Problems with the way in which phpbb.module puts new users into groups

I have done some experimenting as suggested. I disabled the .htaccess file and created a new user directly in phpBB:

My new User was given user_id 64 and was put into a newly-created group with group_id 68. An entry was created in phpbb_user_groups linking these two together.

The newly-created group had a 1 in group_single_user and 'Personal User' in group_description. By contrast, my actual Usergroups have a zero in group_single_user and the name of the Group in group_description.

So - the normal behaviour of phpBB is indeed to create a new group every time a new user is created and link the two together with an entry in phpbb_user_groups though they do not have to be the same number as both auto-increment independently.

This is where I believe phpbb.module is not emulating phpBB's normal behaviour correctly. I do not speak php/mysql well enough to fully understand what it is doing but I believe that it:

1. puts an entry in phpbb_users correctly accepting the auto-incremented user_id offered

2. attempts to put an entry in phpbb_groups incorrectly by forcing acceptance of the same number as offered for user_id instead of accepting the auto-incremented number.

3. Correctly puts an entry in phpbb_user_groups

The incorrect action in 2) does not matter until you create a Usergroup which takes up the next-available group_id number without affecting the user_id sequence. Then, next time a new user is created, the entry into phpbb_groups fails because the group_id number requested has already been taken.

The copy I can find is dated 6th Sept. Is that the one? If not, where do I find the latest copy and what is it dated?

Yes - I've found it now. Many thanks.
