When a user is joining a classroom, created in the standalone site, from an invite link, the JWT token does not contains user id and the resource does not belong to a consumer site. In that case, the user_id parameters set in the join url will be the same for all user using an invite link. With BBB 2.6 it seems that it is not possible anymore to have multiple time the same user with the same user_id. Surprisingly user are ejected once 4 users with the same user_id have joined and they are ejected randomly.
