+.Sh NAME
+.Nm mac.conf
+.Nd Format of the MAC library configuration file
+.Sh DESCRIPTION
+The
+.Nm
+file configures the default label elements to be used by policy-agnostic
+applications that operate on MAC labels.
+.Nm
+contains a series of default label sets specified by object class,
+in addition to blank lines and comments preceded by a
+.Dv #
+symbol.
+.Pp
+Each declaration consists of a single line with two fields separated
+by white space: the object class name, and a list of label elements
+as used by the
+.Xr mac_prepare 3
+library calls prior to an application invocation of a function from
+.Xr mac_get 3 .
+Label element names may optionally begin with a
+.Dv ?
+symbol to indicate that a failure to retrieve the label element for
+an object should be silently ignored, and improves usability if the
+set of MAC policies may change over time.
+.Sh EXAMPLES
+The following example configures user applications to operate with
+four MAC policies:
+.Xr mac_biba 4 ,
+.Xr mac_mls 4 ,
+SEBSD,
+and
+.Xr mac_partition 4 .
+.Bd -literal -offset indent
+#
+# Default label set to be used by simple MAC applications
+#
+
+default_file_labels ?biba,?mls,?sebsd
+default_ifnet_labels ?biba,?mls,?sebsd
+default_process_labels ?biba,?mls,partition,?sebsd
+.Ed
+In this example, userland applications will attempt to retrieve Biba,
+MLS, and SEBSD labels for all object classes; for processes, they will
+additionally attempt to retrieve a Partition identifier.
+In all cases except the Partition identifier, failure to retrieve a
+label due to the respective policy not being present will be ignored.

+.Sh HISTORY
+Support for Mandatory Access Control was introduced in
+.Fx 5.0
+as part of the
+.Tn TrustedBSD
+Project.
+.Sh BUGS
+The
+.Tn TrustedBSD
+MAC Framework and associated policies, interfaces, and
+applications are considered to be an experimental feature in
+.Fx .
+Sites considering production deployment should keep the experimental
+status of these services in mind during any deployment process.
+See also
+.Xr mac 9
+for related considerations regarding the kernel framework.
