[Pkg-shadow-devel] Bug#369439: chgpasswd terminates after asking for a password

[Jonas Meurer]

Package: passwd
Version: 1:4.0.15-10
Severity: normal

hello,

unfortunately, the new chgpasswd tool does not work as expected.
according to docs and it's model 'chpasswd' it reads a string with the
format "group_name:password" from standard input.
obviously, this does not work.

if i execute 'echo "jonas:password" | chgpasswd', i get a prompt:
Password:
and after two seconds it terminates with the following error message:
chgpasswd: PAM authentication failed

chgpasswd should not ask anything, as it's intended to be used in
scripts, and gets all information via stdin.

i am the one who initially submitted chgpasswd to you, and as far as i
remember, you forwarded it to upstream who added it to the shadow/passwd
package. i'm pretty sure that the original version (which was written by
wesley terpstra) worked.

wesley, do you have a copy of the chgpasswd.c that you submitted to me?
