What type of authentication methods are supported by ArcGIS Enterprise?

ArcGIS Enterprise supports multiple authentication methods, which enhances flexibility and security for users accessing the system. The correct answer reflects that ArcGIS Enterprise incorporates named user authentication, token-based authentication, LDAP (Lightweight Directory Access Protocol), and SAML (Security Assertion Markup Language).

Named user authentication allows users to sign in with an ArcGIS Online account or an on-premises account, while token-based authentication is useful for various services that require secure access without needing to repeatedly enter credentials. LDAP integration is vital for organizations using existing directory services for user management, streamlining user access management across the enterprise. SAML provides a way to implement Single Sign-On (SSO), enabling seamless and secure access to ArcGIS Enterprise resources.

Incorporating various authentication methods allows organizations to select the most suitable options based on their requirements for security, user convenience, and integration with existing systems. This support for diverse authentication methods is crucial for accommodating different organizational policies and enhancing user experience.
