I'm not sure I understand the point you're making, possibly due to my=20
misunderstanding how authdaemond works. I thought that the number of=20
child authdaemond processes that were started determined the number of=20
simultaneous login attempts that could be handled, e.g., if daemons=3D5,=20
then one could handle only 5 simultaneous login attempts and no more --=20
additional login attempts would time out and fail. Is this correct? If=20
this is not right, could you explain the relationship between the=20
"daemons" setting and the simultaneous login attempts?
