A company security policy requires all users to log Into applications using a centralized authentication system. Which two authentication, authorization, and accounting (AAA) systems are available when Integrating NSX with VMware Identity Manager? (Choose two.)

NSX supports two types of authentication, authorization, and accounting (AAA) systems when integrating with VMware Identity Manager: RSA SecurID and LDAP and OpenLDAP based on Active Directory (AD). RSA SecurID is a two-factor authentication system that uses a token-based approach to verify the identity of users. LDAP and OpenLDAP based on AD are directory services that store and manage user information and credentials. Both systems can be used to provide centralized authentication for users who want to access applications in an NSX environment . https://blogs.vmware.com/networkvirtualization/2017/11/remote-user-authentication-and-rbacwith-nsx-t.html The integration of VMware Identity Manager with NSX provides the following benefits related to user authentication:
• Support for extensive authentication, authorization, and accounting (AAA) systems, including: — RADIUS — Smart cards and common access cards — RSA SecureID — LDAP and OpenLDAP based on Active Directory (AD)
• Enterprise SSO: — Common authentication platform across multiple VMware solutions — Seamless SSO experience NSX has its own native LDAP and Active Directory integration, but VMware Identity Manager also offers this capability
