RUCKUS SmartZone controllers support three primary types of external Authentication, Authorization, and Accounting (AAA) servers for authenticating network clients. These are Active Directory (AD), Lightweight Directory Access Protocol (LDAP), and RADIUS. AD and LDAP are primarily used as authentication sources, allowing SmartZone to query their user databases. RADIUS is a full-featured AAA protocol that handles authentication, authorization, and accounting services. These services can be configured as either proxy (forwarding requests) or non-proxy (terminating requests) authentication methods depending on the network design.

C. SAML: SAML is supported for specific use cases like administrative Single Sign-On (SSO) or guest portal authentication via an Identity Provider (IdP), not as a general-purpose AAA server for network clients.

D. OAuth: OAuth is an authorization framework used for specific applications, such as social media logins for guest wireless access, but it is not a configurable external AAA server type for general network authentication.

F. TACACS+: TACACS+ is a protocol typically used for device administration (authenticating administrators logging into network equipment) and is not a supported AAA service for client authentication on SmartZone.
