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.)

Awright, egg on my face. I should have taken more time with this. The conversion script generated the wrong format, so the configuration files didn't actually work. Good thing I hadn't thrown the switch yet... Sponsored by: DARPA, NAI Labs (but the f***ups are all mine) 2001-12-05 21:26:00 +00:00			`account required pam_unix.so`

X logins should be recorded in lastlog / wtmp / utmp. I have no idea why this wasn't there already... it makes much more sense this way. MFC after: 2 weeks 2005-04-28 07:59:09 +00:00			`session required pam_lastlog.so no_fail`
the default password policy for xdm should be pam_deny, since it is incapable of holding a meaningful conversation. 2004-02-20 21:59:51 +00:00
