There seems to be a bug with adduser --disabled-password .
With empty password input i get:
$ su test_user
Password:
su: Authentication failure
Only this succeeds:
$ su
Password:
# su test_user
$ whoami
test_user
adduser gave the user this line in /etc/passwd:
test_user:x:<number>:<number>:Test User,,,:/home/test_user:/bin/bash
and in /etc/shadow
test_user:*:17066:0:99999:7:::
Above will not work with users who have /usr/sbin/nologin as shell
"NOLOGIN(8) System Management Commands NOLOGIN(8)
NAME
nologin - politely refuse a login
"
which is used to nail up the user's lines in /etc/passwd like:
backup:x:34:34:backup:/var/backups:/usr/sbin/nologin
resulting in
# su backup
This account is currently not available.
One has to work around by explicitely giving the shell to use
# su backup -s /bin/bash
$ whoami
backup

Does not work for me (at least not out of the box):
$ sudo -u test_user bash
[sudo] password for thomas:
Sorry, user thomas is not allowed to execute '/bin/bash' as test_user on [...]

Have a nice day :)
