Traditional web applications pre-date modern standards like SAML and OpenIDConnect, so they often use legacy authentication methods to grant end users access. Historically, providing Single Sign-On and centralized access management for end users across these legacy applications required a Web Access Management, or WAM, product. These on-premises software tools could be expensive to maintain and complex to deploy. Now, modern identity providers like Okta in conjunction with best-of-breed network management technologies offer a better way. This white paper describes how web applications that lack modern standard support can be integrated into a cloud-based Identity-as-a-service architecture.
