Hey Bret, You can add the "nodelay" option in /etc/pam.d/system-auth: auth sufficient /lib/security/$ISA/pam_unix.so likeauth nodelay I do have a one line source change that removes the need for the above, has zero information leak, and still presents a delay if someone types a password incorrectly. The patch makes the sshd_config option "PermitEmptyPasswords" more meaningful when set to "no". (ie. sshd no longer asks pam if the user can log in without a password). Nobody seems interested in the patch upstream though. If you'd like an updated RPM let me know.
