Imunify360 PAM modules still configured in PAM even after Imunify360 was removed

Symptoms

After removing Imunify360 from your system, you are trying to view a user's crontab, and you come across the following error:

You ($user) are not allowed to access to (crontab) because of pam configuration.

Description 

This error can occur if Imunify360 is not removed cleanly. A partial removal is often caused by using an outdated script to uninstall the software.

Workaround

Reinstalling Imunify360 and uninstalling with the latest script should remove everything cleanly:

1. Access your server using SSH as the root user
2. Use the following command to fetch the latest install script from Imunify:

   wget https://repo.imunify360.cloudlinux.com/defence360/i360deploy.sh -O i360deploy.sh

3. Run the script as the root user:

   bash i360deploy.sh

4. Once the installation is complete, use the following command to confirm the installation was successful and the PAM module is running:

   imunify360-pam status

5. Rerun the install script with the uninstall flag to remove Imunify360:

   bash i360deploy.sh --uninstall

6. Once the removal is completed, you should be able to access crontab once again.
