Integrating Duo with LDAP group mapping in OpenVPN Access Server can be challenging, particularly when merging scripts. Because OpenVPN only supports one post-authentication script, you must guarantee that both functionalities are properlyslice master executed in the same script. Here's a broad strategy to help you troubleshoot and perhaps address the issue. Debugging Tips
Run Independently: Test each function independently to confirm that they work before merging.
Check Logs: Review OpenVPN logs to see if there are any errors or messages related to your script execution.
Add Debug Statements: Include print statements or logging in critical areas to track progress and failures.
- Consolidate Imports: Ensure that all imports from both scripts are at the top of your merged script.
- Define Functions: Ensure that the Duo authentication and LDAP group mapping functions are defined in the script.
- In the main execution block, call the LDAP group mapping function first, followed by the Duo function. This ensures that the LDAP logic is done first.
- Check Return Values: If either function returns a failure, make sure you handle it properly. For example, if the LDAP check fails, you may wish to bypass Duo authentication.
- Logging: Place logging statements throughout the script to determine where it may be failing. This will assist you in determining whether the LDAP component is not being done at all or is failing silently.
