I have put out a support ticket on PHPBB about the issue and got this response.

They can't be using the right password.
If everyone else can get in then the password they use is correct and they have permission to see that forum.
The ones who can't must be doing something wrong as there's no built in way to select a different password for other people. The password is case sensitive. It may also be that their browser is prefilling the field with another password before they type.
They can try deleting their site cookie (with the link at the bottom of the index) in case their browser has cached something.
I know this is not an answer yet but I am still trying to figure it out.... If I have to I will assign groups but this will involve more work than trying to figure out the PW issue.
