Which authentication format supports both local and remote authentications in an Aruba deployment?

In an Aruba deployment, RADIUS (Remote Authentication Dial-In User Service) is the authentication format that supports both local and remote authentications. RADIUS is a widely used protocol that provides centralized authentication, authorization, and accounting management for users who connect and use a network service.

The strength of RADIUS lies in its ability to enable remote authentication, which is particularly useful for organizations that have users connecting from various locations, whether from a VPN, a guest network, or through different network access points. Additionally, RADIUS can be configured to handle local authentication as well, allowing credentials to be stored and verified directly on the network device.

This dual capability makes RADIUS an excellent fit for Aruba networking environments, as it streamlines the authentication process for users whether they are on-site or connecting remotely, providing flexibility and ease of management for network administrators.

Other authentication formats like SAML, LDAP, and OAuth have specific use cases. SAML is primarily used for single sign-on (SSO) and federated identity, while LDAP (Lightweight Directory Access Protocol) is more focused on accessing directory services. OAuth is used primarily for delegated access, allowing applications to access user data without exposing credentials. Each of these has its strengths but does not provide the same
