* Add PAM support to cron(8). Now cron(8) will skip commands scheduledyar2007-06-172-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Now pam_nologin(8) will provide an account management functionyar2007-06-1011-11/+15
| | | | | | | | | | | | | | | | | | | | | | | 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.) PR: bin/112574 Approved by: des, re
