 The SHA solution contains:
 
-* **Application** - BIG-IP published service to be protected by Azure AD SHA. 
-* **Azure AD** - Security Assertion Markup Language (SAML) Identity Provider (IdP) responsible for verification of user credentials, Conditional Access (CA), and SAML based SSO to the BIG-IP. Through SSO, Azure AD provides the BIG-IP with any required session attributes.
-* **BIG-IP** - reverse proxy and SAML service provider (SP) to the application, delegating authentication to the SAML IdP before performing header-based SSO to the backend application.
