Configuring user authentication using SPNEGO

SPNEGO uses a Kerberized environment for user authentication. To use SPNEGO to authenticate users, specify SPNEGO in the user_authentication field.

1. From the Ambari UI, go to Data Analytics Studio > CONFIGS > Advanced data_analytics_studio-security-site.
2. Specify SPNEGO in the user_authentication field.
3. Configure the das_spnego_name_rules field if you have specific name mapping rules for your cluster.
4. Save the changes and restart DAS.
