+ * The following features are recognized:

+ *	=OPENPAM_RESTRICT_SERVICE_NAME:
+ *		Disallow path separators in service names.
+ *		This feature is enabled by default.
+ *		Disabling it allows the application to specify the path to
+ *		the desired policy file directly.
+ *
+ *	=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.
