I am reading this again. I misunderstood the model. This is not an outer 
join. This is an inner join. There is no conflict.

Yet I do not understand. You only select db.groups.name and db.city.name. 
So what you so seem equivalent to this.

groups = db(db.city.id == db.groups.city_id).select(db.groups.name,
db.city.name)

Why join all the other tables? Anyway, try this:

rows = (db.groups.id == db.lab.group_id)(db.lab.id == 
db.researcher_lab_permission.lab_id)(db.researcher.id == 
db.researcher_lab_permission.researcher_id)(db.researcher.user_id == 
db.auth_user.id).select(db.groups.name,db.city.name,db.auth_user.ALL)
