*
* =OPENPAM_VERIFY_POLICY_FILE:
* Verify the ownership and permissions of the policy file
* and the path leading up to it.
* This feature is enabled by default.
*
* =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.
