-------------------------------------------------------------------
Following properties in plugin configuration file (like
{{{}ranger-trino-security.xml{}}}) would trigger the plugin to initialize
UserGroupInformation from the specified keytab. This Kerberos principle will be
used by the plugin to authenticate itself with Ranger admin to download
policies/tags/roles. Also, this principal will be used to authenticate with
HDFS to write audit logs to HDFS.

ranger.plugin.trino.ugi.login.type=keytab

ranger.plugin.trino.ugi.keytab.file=/etc/keytabs/trino.keytab
{noformat}
In addition to above, make sure to have following configurations in place:
# setup Kerberos configuration in /etc/krb5.conf
# {{hadoop.security.authentication=kerberos}} in core-site.xml in the classpath

> Ranger plugin to support configurations to initialize kerberos identity

> Key: RANGER-5116
> URL: https://issues.apache.org/jira/browse/RANGER-5116
> Project: Ranger
> Issue Type: Improvement
> Components: plugins
> Reporter: Madhan Neethiraj
> Assignee: Madhan Neethiraj
> Priority: Major
> Fix For: 3.0.0, 2.6.0
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> In deployments using Kerberos to authenticate with Ranger admin server,
> Ranger plugins use the Kerberos identity returned by
> UserGroupInformation.getLoginUser() to authenticate with Ranger admin server.
> This identity is also used by HDFS audit write to authenticate with HDFS
> services.
> Ranger plugin relies on its host service (like HDFS, Hive, HBase, Knox,
> Impala) to establish the identity in UserGroupInformation. To support
> services that don't use UserGroupInformation (like Trino), the plugin should
> be enhanced to initialize Kerberos identity from its configurations.
