Created attachment 4424
  --> https://bugs.busybox.net/attachment.cgi?id=4424
config file for the buildroot

After building the rootfs it seems that i can't login.
For instance, after the login prompt i type 'root', then it asks for the
password (from what i understand it should have skipped that and show the shell
prompt).

"
Welcome to Buildroot
buildroot login: root
Password: 
Login incorrect

buildroot login: default
Password: 
Login incorrect

buildroot login: 
"

The corresponding config file is included in the attachment.

Can you try disabling BR2_PACKAGE_UTIL_LINUX_AGETTY=y and doing a full rebuild
(make clean; make) ?

We generally only use the getty program from Busybox, so if you use the getty
program from util-linux, there may be a need to adapt certain configuration
files.

Yup,...
It did not help.
I have a feeling it has to do with the WCHAR (the last time i had such a
problem disabling it and everything that depended on it solved the problem).

Can you repost your new .config and confirm that you did a complete "make

sure can.
It's more like:
make clean
make uclibc-menuconfig (to switch on the c99 floating-point support)
make

Can you ask Buildroot to generate a tarball from your root filesystem, and put
it online somewhere (if it doesn't contain anything confidential or
proprietary)?

I think i figures out the cause of the problem.
What should the '/bin/login' be? In the versions that work it points to
'busybox'. In the version that does not work (this version) it's a standard
executable.

Could this be the reason that i can't login?

Ah, yes, good point! /bin/login can be provided by util-linux. I thought about
getty (which I told you already), but I forgot about /bin/login. Can you try
disabling BR2_PACKAGE_UTIL_LINUX_LOGIN_UTILS to see if it works better?

It would be nice to figure out why the /bin/login from util-linux doesn't work.
My initial suspicion would be that it lacks the SUID-root bit set, but on my
system /bin/login doesn't have this bit set. Or maybe the util-linux /bin/login
requires some configuration file that we don't have or something.

Have you tried changing root:x: to root:: in /etc/passwd?

Yup, if i disable BR2_PACKAGE_UTIL_LINUX_LOGIN_UTILS it works (i can login).

Yes, i have. This does make it work (i can login), but since this is a 'hack'
(i don't know why this makes it work) i refrained from using this in our
system.

This should be fixed by commits 72b3c1db513a6235fd5e5f00fb6c15071ffc6015,
33e3245e047858cd89223cf5b4afbf4cb32318b0 and
1a0b170a55126115d883f6cde9871e06a80f9cc2 (maybe i'm missing some other) for the
2014.02 release.
If you're still seeing issues with this feel free to reopen this bug with the
details (and using a latest git version). Thanks.

Please do not reopen an old case just because you see a similar problem six
years later. Both Buildroot and util-linux changed a lot since 2012. Open a new
bug and attach your defconfig, as well as other information that can be useful
to reproduce your problem, instead.
