useradd command with -p option (cannot login to new account)


Hi. I've tried creating a new user account with custom options and everything works fine except for the password. I couldn't login when I created a password using the "-p {password} option. I had to login as a different user and change the password with the sudo passwd {username} command.

As stated in the useradd manpage:
Quote:
-p, --password PASSWORD
The encrypted password, as returned by crypt(3).
Use the passwd command to set/change the users password.

You could also create a small binary yourself using the crypt() function.

You'll have to encrypt the password first and then pass the hash to useradd with the -p option. You can use openssl to generate the hash/salt:
Code:
user@linux:~$ openssl passwd -1 SecretPassword
$1$9tYqclBf$dW1jWQVk.9FEck02WLrc3.
user@linux:~$ sudo useradd -p $1$9tYqclBf$dW1jWQVk.9FEck02WLrc3. newuser
The user newuser will now be able to log on with the password SecretPassword.
