なければならない states plain necessity and lives at every register; ざるを得ない is written and formal, and always concedes reluctance — circumstances, not duty, force the act, so 認めざるを得ない admits under pressure where 認めなければならない merely cites obligation.
Both mean "forced to do" — させられる names a forcer (a person makes you), ざるを得ない blames circumstances with no one to point at; 残業させられた has a boss in it, 残業せざるを得ない only a deadline.
