Not being much familiar with Dropbear, I'm wondering if it supports
PAM [1]? If it does, can it work with a similar PAM config file like I
am supplying* with Busybox for login i. e.

auth      required       pam_unix.so nullok
account   required       pam_unix.so nullok
password  required       pam_unix.so nullok
session   required       pam_unix.so nullok

with such PAM config file zero-length passwords are allowed. Busybox
login works this way for users `default' and `root' but not for any
other username.

committed  yet:

Thanks.
