Your installation of Platform Services includes an uninstall script for easy removal of the product from a target platform.
If you have configured your system to use the Fan-Out Driver PAM module for authentication, make sure you first remove the Fan-Out Driver Platform Services module, ascauth, from your PAM configuration before uninstalling the product. Leaving PAM with invalid library references can leave your system in an unpredictable state for new logon requests.
To uninstall Platform Services, run the following script:
/usr/local/ASAM/bin/PlatformServices/plat-uninstall
