66 * EXPERIMENTAL
67 *
68 * The =openpam_get_feature function stores the current state of the
69 * specified feature in the variable pointed to by its =onoff argument.
70 *
71 * The following features are recognized:
72 *
73 *	=OPENPAM_RESTRICT_SERVICE_NAME:
74 *		Disallow path separators in service names.
75 *		This feature is enabled by default.
76 *		Disabling it allows the application to specify the path to
77 *		the desired policy file directly.
78 *
79 *	=OPENPAM_VERIFY_POLICY_FILE:
80 *		Verify the ownership and permissions of the policy file
81 *		and the path leading up to it.
82 *		This feature is enabled by default.
83 *
84 *	=OPENPAM_RESTRICT_MODULE_NAME:
85 *		Disallow path separators in module names.
86 *		This feature is disabled by default.
87 *		Enabling it prevents the use of modules in non-standard
88 *		locations.
89 *
90 *	=OPENPAM_VERIFY_MODULE_FILE:
91 *		Verify the ownership and permissions of each loadable
92 *		module and the path leading up to it.
93 *		This feature is enabled by default.
