Glossary
Definitions for commonly used terms in MapR Converged Data Platform environments.

Authentication Enhancements for Ticket Handling

Describes limitations in the MapR-SASL authentication mechanism for earlier releases and the enhancements to the mechanism for release 7.0.0.

With these enhancements, applications that are not cluster aware can still authenticate with other clusters. Client applications that need to authenticate with a non-default cluster using MapR-SASL now automatically select the correct ticket if the user has a valid ticket for that cluster.
