Error executing Automation Services jobs on Server

Error executing Automation Services jobs on Server

Executing the Automation Service jobs on server might fail when using Kerberos Authentication. The following error can be seen in the Automation logs.
==========
Failure acquiring a Kerberos TGT, no JAAS application configuration is configured
========== 1) Export the Automation services configuration using the "export-service-config" command.

2) Open the "Spotfire.Dxp.Automation" file in a text editor.

3) Look for the following section and make sure that it has the "useKerberos" set to "true", with the "kerberosIdentity userName" and "password" defined. The username and password here are the Kerberos service account username and password.
==========
<automation maxWaitTimeForTaskBackgroundJobToFinishSeconds="180" maxConcurrentJobs="-1" useKerberos="true">
    <kerberosIdentity userName="USERNAME" password="PASSWORD" />
==========

4) If these elements are not present, add them in the config file so it looks as below.
==========
<Spotfire.Dxp.Automation>
    <!-- maxWaitTimeForTaskBackgroundJobToFinishSeconds: -->
    <!--    The number of seconds to wait for background thread execution to finish after the task finished executing. -->
    <!-- maxConcurrentJobs: -->
    <!--    Number of jobs that are allowed to execute in parallel. If 0 or less, this is set to the number of cpu cores on the machine. -->
    <automation maxWaitTimeForTaskBackgroundJobToFinishSeconds="180" maxConcurrentJobs="-1" useKerberos="true">
    <kerberosIdentity userName="USERNAME" password="PASSWORD" />
    </automation>
</Spotfire.Dxp.Automation>
==========

4) Save the file.

5) Import the configuration back using "import-service-config" command.

6) Apply this imported configuration to the Automation Services in Administrator UI console.
