零改造的认证迁移方案设计与实现OA

This paper proposes a zero-modification authentication migration scheme based on gateways,aimed at addressing the challenge of seamlessly upgrading to a new commercial authentication platform in complex system environments.Its core lies in using a service gateway with dynamic routing capabilities as the central hub,which adapts to CAS protocol requests and progressively shifts traffic from the legacy authentication system to the new commercial platform through a whitelist mechanism.Simultaneously,unified LDAP directory services enable authentication across both old and new systems.Through multi-replica gateway deployment,gray scale traffic switching,and comprehensive rollback mechanisms,it ensures a user-transparent migration process,progressively phasing business systems into the new authentication platform.This scheme is universally applicable,providing a reusable technical framework for upgrading university authentication systems,significantly reducing migration costs and business risks.
