I just installed gentoo from ubuntu.
I rebooted and select gentoo, try to login with the root password set in gentoo install process.

The problem is that I cannot login with the password.

I also created ordinal user in chroot-ed environment, and set password, but I cannot login with it either.

Both passwords are longer than 8 letters, and show no strength warning.

If I login as root with chroot from ubuntu, then
Code:
 su - username
, and
Code:
 su
, I can use the passwords. All go successfully.

Let me know how to debug this issue

The error messages are like:
Authentication failure
Quote:
pam_unix(login:auth): authentication failure; logname=LOGIN uid=0 euid=0 tty=/dev/tty1 ruser= rhost= user=root
FAILED LOGIN (1) on '/dev/tty1' FOR 'root', Authentication failure


I checked following threads, but nothing helped me.

boot cd,
if ubuntu
Code:
sudo su --
mkdir /mnt/gentoo

mount the gentoo partitions, enter the chroot, nominally:
Code:
mount /dev/sda3 /mnt/gentoo
mount /dev/sda1 /mnt/gentoo/boot
cp /etc/resolv.conf /mnt/gentoo/etc/resolv.conf
mount -t proc none /mnt/gentoo/proc
mount -o bind /dev /mnt/gentoo/dev
chroot /mnt/gentoo /bin/bash
env-update
source /etc/profile
export PS1="(chroot) $PS1"
passwd
create root password
Code:
exit
reboot

Thanks for reply.

I've already followed these steps.

But, I booted with rescue mode, set the same password, and rebooted,then I came to be ale to login!!

I have no idea why the root password is not correctly set from Ubuntu.

Anyway, the problem is solved :-)
