     70  * The =openpam_get_feature function stores the current state of the
     71  * specified feature in the variable pointed to by its =onoff argument.
     72  *
     73  * The following features are recognized:
     74  *
     75  *	=OPENPAM_RESTRICT_SERVICE_NAME:
     76  *		Disallow path separators in service names.
     77  *		This feature is enabled by default.
     78  *		Disabling it allows the application to specify the path to
     79  *		the desired policy file directly.
     80  *
     81  *	=OPENPAM_VERIFY_POLICY_FILE:
     82  *		Verify the ownership and permissions of the policy file
     83  *		and the path leading up to it.
     84  *		This feature is enabled by default.
     85  *
     86  *	=OPENPAM_RESTRICT_MODULE_NAME:
     87  *		Disallow path separators in module names.
     88  *		This feature is disabled by default.
     89  *		Enabling it prevents the use of modules in non-standard
     90  *		locations.
     91  *
     92  *	=OPENPAM_VERIFY_MODULE_FILE:
     93  *		Verify the ownership and permissions of each loadable
     94  *		module and the path leading up to it.
     95  *		This feature is enabled by default.
