Dramatically Improving Support for Role Providers in DataStax Enterprise Unified Authentication

The latest version of DataStax Enterprise (DSE) introduces an enhancement to its Unified Authentication connectivity suite, allowing the DSE Authorizer to leverage multiple role managers. This feature increases application flexibility and brings a design improvement in the DSE architecture. Before this enhancement, the LDAP system would become a single point of failure if DSE was configured to use it as the role provider. With the latest enhancement, the DSE Authorizer can be configured to utilize multiple role managers that are designated to the corresponding authentication mechanisms. This avoids a SPOF because the external group is the only group reliant on LDAP’s availability, which is more desirable. The enhancement is optional and has also been backported to DSE 5.1.21, 6.0.15, and 6.7.13.
