Resolution

Follow below steps to resolve the error.

1. Uncomment the below parameter on the Agent ini 

 authentication=pam

2. The agent requires a service file in the /etc/pam.d/ directory that matches the name of the agent's binary (e.g., ucxjlx6 for the Linux agent).

Action: Create a file in /etc/pam.d/ with the same name as your agent's binary. For a standard Linux agent, the file would be /etc/pam.d/ucxjlx6.
Content: Add the following lines to this new file. This configuration tells PAM to use the standard system-wide authentication policies for the agent.
#%PAM-1.0 auth include system-auth account include system-auth password include system-auth
Permissions: Ensure the file is owned by root and has appropriate read permissions.

After creating this file and confirming the .ini setting, restart the agent and run the job again.
