Bug 338591 – sys-apps/shadow-4.1.4.2-r5 stable request

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Robin Johnson 2010-09-24 19:50:32 UTC]

This bug caused me to be locked out of a new system I installed, as I had to root it myself because none of the passwords got set due to this bug.

# grep foo /etc/shadow ; echo foo:awjaxcewFatNusEyb |chpasswd ; echo $? ; grep foo /etc/shadow
foo:!:14868:0:99999:7:::
0
foo:!:14868:0:99999:7:::

Expected result:
That chpasswd actually sets the password for the user.

I've tried with and without NSCD, same result. Nothing in log outputs at all.
Also weirdly, the manpage for chpasswd lists multiple options, but the --help does not.

# chpasswd --help
Usage: chpasswd [options]

Options:
  -h, --help                    display this help message and exit

I can confirm this on x86 too and this reminds me of bug 275555 but that fixed doesn't seem to remedy this. Have you tried with -pam to see if chpasswd works?

[Comment 2 SpanKY 2010-09-24 20:25:29 UTC]

works fine on my USE=-pam systems.  are you sure Bug 275555 doesnt fix it ?  that change isnt in current stable.

[Comment 3 Diego Elio Pettenò (RETIRED) 2010-09-24 20:29:43 UTC]

Changing to a stable request, the bug was fixed but it hasn't hit stable yet.

No that doesn't fix it, tried it and chpasswd is still not applying password changes, but I will let robbat2 confirm on his end.

[Comment 5 Fernando (likewhoa) 2010-09-24 20:43:31 UTC]

yea ma bad, i was editing the wrong file /etc/pam.d/shadow instead of /etc/pam.d/chpasswd

[Comment 6 David Abbott (RETIRED) 2010-09-24 21:24:34 UTC]

All good x86.

Removing infra since this is fixed on x86/amd64 for us.

[Comment 14 Gustavo A. Díaz 2010-10-12 17:51:20 UTC]

Guys...

This is not working for me yet, even with -r5 installed (I've reported same in #275555):

# echo "user:password" | chpasswd -m

chpasswd: invalid option -- 'm'

[Comment 15 SpanKY 2010-10-12 18:41:24 UTC]

do not go spamming unrelated issues to multiple bugs.  plus, this is a stabilization bug, not a report bug.
