During the installation process, you will set up the authentication method for to the HDP Security Administration Web UI. The Web UI supports the following authentication methods:
Local HDP Security Administration Web UI user database: Users and their credentials are stored in the HDP Security Administration database, and managed manually in the interface.
External LDAP (supported services are OpenLDAP or AD): Users authenticate against an external LDAP service and their permission is determined by their group membership. Requires configuration during installation of the HDP Security Administration tools.
External Unix Server: Users authenticate against an external Unix system using their credentials for that remote Unix system. Typically this is a server within the Hadoop cluster. This also requires configuration during both the installation of the HDP Security Administration tools and the installation of the Users and Groups Synchronizer Agent on the remote Unix System.
