The ! for the password in /etc/shadow indicates that the account is
disabled:
sakura:!:18031:0:99999:7:::
Either there is something wrong with the password generation or it gets
disabled by something else. Maybe it's worth trying with a plain image
without Boot2Qt or anything else.

Hi Rudolf,
1st, yes I inherit extrausers. Attached are the passwd & shadow files.
It shouldn't make any difference, but I'm building this for an RPi3
using the Qt Boot2Qt version of the Yocto environment, distro 2.5.3.

Hi Greg,

Help me to understand this. the back-quotes are the right ones. If you
use the single ones your password in the /etc/shadow ends up being
'openssl passwd test' (without the quotes), unless the build fails
because of a parsing error (I have not tried it). Silly question, you
did inherit extrausers class?
Can you post your /etc/passwd and /etc/shadow
I am surprised that this does not work with your setup. I have been
doing this a gazillion times always with success.

Hi Rudolf,
Thanks for the reply, and the information on how openssl works.
I'm trying to create a user with the same group name so the code that
I'm using reduces to:
EXTRA_USERS_PARAMS = "\
useradd -p `openssl passwd test` sakura; \
usermod -a -G sudo ${SAKURA_USER}; \
"
I also, as you can see, removed the macros to eliminate as much
confusion as possible.
I still can't login in using the password 'test'.
I've also tried both the back-quote and the single-quote, no difference.
Regards,
Greg

Hi Greg,
Well, I suppose I wrote the book you are referring to...
Using
useradd -p PASSWORD USER
takes the password hash for PASSWORD hence the use of openssl in:
useadd -p `openssl passwd PASSWORD` USER
openssl password creates the password hash using the original crypt hash
algorithm if no other options are specified. e.g.
$ openssl passwd hello
6hEsTksgRkeiI
With this the first two characters of the output is the salt and the
rest is the password hash. If you want openssl to create the same result
again:
$ openssl passwd -salt "6h" hello
6hEsTksgRkeiI
You can use newer algorithms like MD5 based BSD password algorithm 1:
$ openssl passwd -1 hello
$1$4Mu8Fcs.$eIKgPP7RCYrb3lFZjhADA1
$1 : password algorithm 1
$4Mu8Fcs. : salt
$eIKgPP7RCYrb3lFZjhADA1 : password hash
If you log into the system you have to use the clear password. The
system reads the salt, creates the password hash and compares the
results.
