Which authentication method is used for integration with LDAP?

The correct choice involves understanding the integration of CyberArk with directory services like LDAP (Lightweight Directory Access Protocol). LDAP is commonly used for directory services, allowing users and applications to access and manage user information over a network.

PKI (Public Key Infrastructure) authentication, which uses digital certificates for secure authentication, can work in conjunction with LDAP by validating user identities through certificates. This allows for a secure communication channel between CyberArk and the LDAP server. LDAP can be used to store and manage user credentials and access rights, and PKI can leverage those stored credentials to authenticate users securely.

While Windows authentication is specific to environments using Windows domain credentials and isn't designed solely for LDAP, Amazon Cognito is more of a cloud service focused on user identity and resource access management, which does not directly relate to traditional LDAP integrations. The option indicating "None of the above" does not align since PKI is indeed a method used for such integrations. Thus, the choice of PKI Auth stands out as the method distinctly associated with LDAP integration in the context of CyberArk.
