+.Os
+.Sh NAME
+.Nm mac_seeotheruids
+.Nd "simple policy controlling whether users see other users"
+.Sh SYNOPSIS
+To compile the
+policy into your kernel, place the following lines in your kernel
+configuration file:
+.Bd -ragged -offset indent
+.Cd "options MAC"
+.Cd "options MAC_SEEOTHERUIDS"
+.Ed
+.Pp
+Alternately, to load the module at boot time, place the following line
+in your kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "options MAC"
+.Ed
+.Pp
+and in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent
+mac_seeotheruids_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+policy module, when enabled, denies users to see processes or sockets owned
+by other users.
+.Pp
+To enable
+.Nm ,
+set the sysctl OID
+.Va security.mac.seeotheruids.enabled
+to 1.
+To permit superuser awareness of other credentials by virtue of privilege,
+set the sysctl OID
+.Va security.mac.seeotheruids.suser_privileged
+to 1.
+.Pp
+To allow users to see processes and sockets owned by the same primary group,
+set the sysctl OID
+.Va security.mac.seeotheruids.primarygroup_enabled
+to 1.
+.Pp
+To allow processes with a specific group ID to be exempt from the policy,
+set the sysctl OID
+.Va security.mac.seeotheruids.specificgid_enabled
+to 1, and
+.Va security.mac.seeotheruids.specificgid
+to the group ID to be exempted.

+.Sh HISTORY
+The
+.Nm
+policy module first appeared in
+.Fx 5.0
+and was developed by the
+.Tn TrustedBSD
+Project.
+.Sh AUTHORS
+This software was contributed to the
+.Fx
+Project by Network Associates Labs,
+the Security Research Division of Network Associates
+Inc.
+under DARPA/SPAWAR contract N66001-01-C-8035
+.Pq Dq CBOSS ,
+as part of the DARPA CHATS research program.
+.Sh BUGS
+See
+.Xr mac 9
+concerning appropriateness for production use.
+The
+.Tn TrustedBSD
+MAC Framework is considered experimental in
+.Fx .
+.Pp
+While the MAC Framework design is intended to support the containment of
+the root user, not all attack channels are currently protected by entry
+point checks.
+As such, MAC Framework policies should not be relied on, in isolation,
+to protect against a malicious privileged user.
