Resolving the CyberArk ITATS004E Authentication Failure in Python Scripts
When working with remote machines and using CyberArk for secure connections, you may encounter the ITATS004E Authentication failure for User error while executing SSH commands from a Python script. This error can disrupt your workflow and leave you wondering about its cause. In this guide, we will explore this problem in detail and provide a structured solution to help you avoid authentication failures in your scripts.
Understanding the Problem
What is the ITATS004E Error?
The ITATS004E error signifies an authentication failure when trying to connect through CyberArk's Password Security Management (PSM). The error message often appears while establishing an SSH connection to a remote server via a proxy. Notably, this issue tends to occur sporadically, which can make it perplexing to troubleshoot.
The Symptoms
Typically, you'll observe the following symptoms when you encounter this error:
The SSH command fails, resulting in an exit code of 255.
You may not find any relevant errors in the SSH logs on the remote server.
Running the same SSH command manually from the terminal succeeds without issues, raising doubts about the script's execution.
Common Causes
Some of the potential causes for this error could include:
A misconfigured known_hosts file causing connection issues.
Temporary network issues leading to intermittent authentication failures.
Limitations related to how the script handles SSH connections, specifically in the subprocess execution.
Implementing a Solution
Approach Overview
To mitigate the random authentication failures, we can implement a retry mechanism that resets the known_hosts file and re-attempts the SSH connection a specified number of times. This approach helps to accommodate temporary inconsistencies during connection attempts.
Step-by-Step Implementation
Here’s how to structure the solution in your Python script:
1. Define the Command Execution Function
Firstly, create a function that encapsulates the logic for executing shell commands:

2. Setting Up the Retry Logic
Next, implement a while loop to retry the SSH command execution:

Explanation of the Retry Logic
Known Hosts Reset: Each retry cycle begins by resetting the known_hosts entries for the proxy. This helps to avoid issues arising from outdated or incorrect entries in the file.
Using sshpass: This allows passing the password automatically, managing the authentication process without manual interruptions.
Output Handling: If the SSH command fails, the loop sleeps for 15 seconds before retrying, giving the system a brief pause to recover from transient issues.
Conclusion
Encountering the CyberArk ITATS004E Authentication failure error can be quite frustrating, especially when it occurs unpredictively. By implementing a retry mechanism that handles known_hosts resets and providing automated password handling, you can significantly increase the reliability of your Python scripts when executing SSH commands via CyberArk.
If you continue to experience issues, consider reviewing CyberArk settings or consult with your system administrator for deeper insights. By being proactive and systematic about troubleshooting, you can enhance your scripting experience.
