OPENPAM_RESTRICT_MODULE_NAME
    Disallow path separators in module names. This feature is disabled by default. Enabling it prevents the use of modules in non-standard locations.

OPENPAM_VERIFY_MODULE_FILE
    Verify the ownership and permissions of each loadable module and the path leading up to it. This feature is enabled by default.
