I used install{kernel,world} and mergemaster. sshd_config is
overwritten to new one(may /usr/src/crypto/openssh/sshd_config),
pam.conf is overwritten also(I didn't touch sshd_config and pam.conf
before, and I usually does not touch), and UPDATING doesn't say much
about this thing.

I know. But I upgraded kernel and userland, so someday I must reboot
to finalize upgrade procedure. And when I rebooted without touching
anything, all problem goes out and I can login into the server without
touching sshd_config or pam.conf. In my not-so-long freebsd
experience it is very rare event so I am confused very much.
