+### Client Authentication with Kerberos
+
+Kerberos is far and away the de-facto means provide strong authentication across Hadoop
+and other related components. Kerberos uses requires a centralized key distribution center
+to authentication users who have credentials provided by an administrator. When Hadoop is
+configured for use with Kerberos, all users must provide Kerberos credentials to interact
+with the filesystem, launch YARN jobs, or even view certain web pages.
+
+While Accumulo has long supported operation on Hadoop with Kerberos enabled, it required
+Accumulo users to still use password-based authentication. [ACCUMULO-2815][ACCUMULO-2815]
+added support to Accumulo to allow Accumulo clients to use a single set of Kerberos
+credentials to interact with Accumulo and all other Hadoop components.
+
+This authentication leverages the [Simple Authentication and Security Layer (SASL)][SASL]
+and [GSSAPI][GSSAPI] to support Kerberos authentication over the existing Thrift-base
+RPC infrastructure that Accumulo leverages.
+
+These additions represent a significant forward step for Accumulo, bringing it up to
+speed with the rest of the Hadoop components. This results in a much more cohesive
+security story for Accumulo that resonates with the battle-tested cell-level security
+and authorization module.
