Which of the following are Single Sign-On (SSO) authentication options in a SonicWall firewall?

Single Sign-On (SSO) authentication allows users to log in once and gain access to multiple systems without needing to re-enter their credentials. In the context of SonicWall firewalls, SSO is typically utilized to improve user experience and simplify management.

LDAP (Lightweight Directory Access Protocol) is indeed a recognized option for SSO authentication within SonicWall devices. When configured, it enables the firewall to authenticate users against an existing directory service, such as Active Directory. This integration not only streamlines the authentication process for users but also allows administrators to manage access control based on centralized user management systems.

Using LDAP for SSO means that once a user logs into the directory service, they can seamlessly access the resources protected by the SonicWall firewall without being prompted to log in again, hence enhancing security and user convenience.
