Secure impersonation directly from the following is not supported:

• PDI client

• Scheduled Jobs and Transformations

• Pentaho Report Designer

• Pentaho Metadata Editor

• Kitchen

When you run a transformation or job to run against the cluster from the PDI client, you cannot use secure impersonation. However, if you execute that job or transformation you created in the PDI client from the Pentaho Server, then you can use secure impersonation.
