Hoseok Seo discusses configuring access to the Kubernetes Dashboard using OKTA for authentication. OKTA allows IT to manage employee access to any application from a central location. LDAP (Lightweight Directory Access Protocol) is a standard for accessing and managing directory services like Active Directory, facilitating sharing of user and system information between applications that need it. OKTA provides directory services with an LDAP interface that can be used to authenticate with applications like the Kubernetes Dashboard using the kubernetes-dashboard-auth plugin on GitHub.
