10d3ca6e6d Remove this file. It is no longer needed as x11/gdm provides its own
version under /usr/local/etc/pam.d.

997c6eefd8 Add PAM support to cron(8). Now cron(8) will skip commands scheduled
by unavailable accounts, e.g., those locked, expired, not allowed in at
the moment by nologin(5), or whatever, depending on cron's pam.conf(5).
This applies to personal crontabs only, /etc/crontab is unaffected.

In other words, now the account management policy will apply to
commands scheduled by users via crontab(1) so that a user can no
longer use cron(8) to set up a delayed backdoor and run commands
during periods when the admin doesn't want him to.

The PAM check is done just before running a command, not when loading
a crontab, because accounts can get locked, expired, and re-enabled
any time with no changes to their crontabs.  E.g., imagine that you
provide a system with payed access, or better a cluster of such
systems with centralized account management via PAM.  When a user
pays for some days of access, you set his expire field respectively.
If the account expires before its owner pays more, its crontab
commands won't run until the next payment is made.  Then it'll be
enough to set the expire field in future for the commands to run
again.  And so on.

Document this change in the cron(8) manpage, which includes adding
a FILES section and touching the document date.

X-Security: should benefit as users have access to cron(8) by default

b1cf245735 Locked out and expired accounts shouldn't be accessible via remote
mailbox protocols.  Add pam_unix to the `account' function class, too,
for imap and pop3 to actually implement this policy.

9cd40e64b4 Now pam_nologin(8) will provide an account management function
instead of an authentication function.  There are a design reason
and a practical reason for that.  First, the module belongs in
account management because it checks availability of the account
and does no authentication.  Second, there are existing and potential
PAM consumers that skip PAM authentication for good or for bad.
E.g., sshd(8) just prefers internal routines for public key auth;
OTOH, cron(8) and atrun(8) do implicit authentication when running
a job on behalf of its owner, so their inability to use PAM auth
is fundamental, but they can benefit from PAM account management.

Document this change in the manpage.

Modify /etc/pam.d files accordingly, so that pam_nologin.so is listed
under the "account" function class.

Bump __FreeBSD_version (mostly for ports, as this change should be
invisible to C code outside pam_nologin.)

a8e0b2e8ab Remove rexecd(8), a server that implements a particularly insecure
method of executing commands remotely.  There are no rexec clients in
the FreeBSD tree, and the client function rexec(3) is present only in
libcompat.  It has been documented as "obsolete" since 4.3BSD, and its
use has been discouraged in the man page for over 10 years.

c3d7aa730d Add a system policy, and have the login and su policies include it rather
than duplicate it.  This requires OpenPAM Dianthus, which was committed two
weeks ago; installing these files on a system running a world older than
June 1st, 2003 will cause login(1) and su(1) to fail.

64ac587b8a Exempt the "wheel group requirement" by default when su'ing to root if
the wheel group has no explicit members listed in /etc/group.  This adds
the "exempt_if_empty" flag to pam_wheel in the default configuration;
in some environments, it may be appropriate to remove this flag, however,
this default is the same as pre-pam_wheel.

48988cd4bd xdm plays horrid tricks with PAM, and dumps core if it's allowed to call
pam_lastlog, so add a dummy session chain to avoid using the one from
pam.d/other.  I assume gdm does something similar, so give it a dummy
session chain as well.

5b3e868df5 Fixed bugs in previous revision:
Added NOOBJ if anyone even attempts to "make obj" here.
Revert to installing files with mode 644 except README.
Make this overall look like a BSD-style Makefile rather
than roll-your-own (this is not a bug).

For the record.  Previous revision also fixed the breakage
introduced by the sys.mk,v 1.60 commit: bsd.own.mk is no
longer automatically included from sys.mk.
