Learn how to provide the Kerberos credentials by defining the Keytab Credentials Controller Service.
In most processors there are two ways to provide the Kerberos credentials: either via properties directly available in processor's configuration (this is the legacy way) or via the definition of a Keytab Credentials Controller Service. The controller service is the recommended way in multi tenant environments where access to keytab configuration should be managed independently between different teams.
Setting this value to
false will produce a validation error in any component
where the free-form keytab property is entered, which means the component cannot be started
unless it uses a Keytab Controller service.
This environment variable set to false in combination with the
/restricted-components/access-keytab policy is the recommended way to have the
finest grained control over keytabs.
