I earlier queried about the-p option of useradd. After realising that -p
need the encrupted passwd I thought I had had it solved. However, it is
not working. I am curious to a few points and I will try to explain it as
breifly as possible.
1) I need to add MD5 passwds all in one shot.
2) the command string looks like this:
useradd -g mailusers -d /email_dirs/n/newuser -p
$1$U9BZsc8v$84Kz5LPldJz.Rzgxm8oI71 newuser
However, useradd only passes the last 21 digits into /etc/shadow
newuser:4Kz5LPldJz.Rzgxm8oI71:10939:0:99999:7:::
3) MD5 passwords are enabled. If I set the passwd seperatley, (above
passwd is qwer1234, and is a valid MD5 passwd) it will make an MD5 passwd:
root@gradishar /tmp]# passwd newuser
Changing password for user newuser
New UNIX password:<qwer1234>
Retype new UNIX password:<qwer1234>
passwd: all authentication tokens updated successfully
/etc/shadow:
newuser:$1$nCYfNe8b$HoPOs4KzQCDaB63KCYqW..:10939:0:99999:7:-1:-1:134538444
(note* the below works too as they are same pw, different salts)
newuser:$1$U9BZsc8v$84Kz5LPldJz.Rzgxm8oI71:10939:0:99999:7:-1:-1:134538444
4) here is another quirky thing, the -p option is not even documented in
my useradd >man useradd:
USERADD(8) USERADD(8)
NAME
useradd - Create a new user or update default new user information
SYNOPSIS

but, it is included in useradd by itself
[root@gradishar /tmp]# useradd

[-f inactive] [-e expire mm/dd/yy] [-p passwd] [-n] [-r]
name
useradd -D [-g group] [-b base] [-s shell] [-f inactive] [-e
expire mm/dd/yy]
I could not determine what version I have. However, I am running RH60
Linux gradishar 2.2.5-15 #1 Mon Apr 19 22:21:09 EDT 1999 i586 unknown
Please advise as I need to be able to add users and passwds automatically.
Thanks
