Amazon EMR is excited to announce a new feature that enables user authentication to EMR on EC2 clusters using Lightweight Directory Access Protocol (LDAP) based credentials. This feature allows administrators to configure EMR on EC2 clusters to authenticate corporate identities in their Active Directory (AD) using LDAP. With this launch, AD users are synced to the EMR on EC2 cluster automatically when LDAP authentication is enabled. This simplifies authentication to EMR clusters for administrators by eliminating the manual steps to sync users and/or implementing application-specific LDAP configuration.
Amazon EMR on EC2 customers create and manage their corporate user identities and groups in an LDAP directory based service such as AD or openLDAP. With native LDAP integration, end users can authenticate to EMR clusters using their AD credentials and use applications such as Hue, Presto and Livy to run jobs as themselves. This simplifies user authentication with EMR on EC2 clusters using AD and allows corporate users to launch queries and sessions on applications such as Hue, Presto using their LDAP based credentials. Prior to this launch, administrators configured Kerberos to authenticate AD users which is manual and effort-intensive. With this launch, administrators can also enforce fine-grained access control (FGAC) for AD users through Apache Ranger authorization for Hive Metastore database and tables.
