+.Sh NAME
+.\" .Cd options MAC_BSDEXTENDED
+.Nm mac_bsdextended
+.Nd mandatory rules regarding users and system objects
+.Sh SYNOPSIS
+.Li kldload mac_bsdextended
+.Sh DESCRIPTION
+The
+.Nm
+interface provides an interface for the system administrator
+to impose mandatory rules regarding users and some system objects.
+Rules are uploaded to the module
+(typically using
+.Xr libugidfw 3 )
+where they are stored internally
+and used to determine whether to allow or deny specific accesses
+(see
+.Xr ugidfw 8 ) .
+.Sh IMPLEMENTATION NOTES
+While the traditional
+.Xr mac 9
+entry points are implemented,
+policy labels are not used;
+instead, access control decisions are made by iterating through the internal
+list of rules until a rule
+which denies the particular access
+is found,
+or the end of the list is reached.
+.Sh SEE ALSO
+.Xr libugidfw 3 ,
+.Xr ugidfw 8 ,
+.Xr mac 9
+.Sh HISTORY
+The
+.Nm
+interface was first introduced in
+.Fx 5.0 .
