Password Issue

[UniRock]

Hi All,

I am trying to create a new user "test" UID=0 from root. Following is what happens:

---------------------------------------
# useradd -o -u 0 -m -d /home/test test
# passwd test
Changing password for test
Old password:
Sorry.
---------------------------------------

Why is it asking for old password, when it is a 'brand' new user?
Is is because this is a trusted system?

Response is much appreciated.


Thanks..
UniRock

Hello UniRock

can you check your /etc/passwd file the test user already exist?

if it not exist please update /etc/passwd file with below line and then on command prompt type passwd test to reset password.

test::0:0:test user:/test:/bin/bash

let me know how it goes, thanks,

[UniRock]

Hi Avizen,

It exists already..
test:*:104:20::/home/test:/sbin/sh

Shall I modify it and try?

[UniRock]

Sorry,
It was:

test:*:0:20::/home/test:/sbin/sh

Hi,

open this file /tcb/files/auth/t/test


test:u_name=test:u_id#0:\
:u_pwd=encrypted_password:\
:u_minchg#0:u_pickpw:u_nullpw:u_restrict@:\
:u_maxtries#100:u_lock@:chkent:

delete all cherecter after "=" sign on this line after deleteing this look like the below line
u_pwd= :\

save the file

try with "passwd test"

now it will not ask the old passwd

Hi Suraj,

The file looks like:

test:u_name=test:u_id#0:\
:u_pwd=*:\ <<<======
:u_auditid#16:\
:u_auditflag#1:\
:u_unsucchg#1242269911:u_suclog#1242269865:u_lock@:chkent:

[avizen9]

can you remove * also and then try, please take backup for this file before modify anyting, thanks,

u_pwd=*:\ <<<======

[UniRock]

Still no luck.....same results :(

Dear Friend
what about u system is it trusted or not trusted. if it is trusted

do the following

passwd â df userid.

once u entered this command next time user login will ask new passwd only

thanks and regards

Hi Sajjad,

UserId is 0....as i am trying to create another user with root powers.

Still if I use the command, I get:

# passwd -df 0

Password cannot be changed. Reason: Cannot access protected password entry.

[Sajjad Sahir]

the same user what asked old passwd

that one try first

by using this command

passwd -df new122


then open another terminal session
try to enter the user which one u forgot the passwd

thanks and regards

Hi UniRock,

Are you creating a NEW user with UID 0.....or this is an OLD/existing user??

[Ganesan R]

Hi,

Never create a user with uid 0.

Think if you remove the user later point of time along with user owned files delete option. It delete all the root owned files as well.

So it is not recommanded to have user with uid 0

[Suraj K Sankari]

Hi,

After deleteing the * save the file
give passwd test

Hello All,

Removing * from below line solved the issue :)
u_pwd=*:\ <<<======

Actually first I tried this and failed.
u_pwd= :\ <<=== space before colon

Later, I tried this and succeeded.
u_pwd=:\ <<<==== no space before colon.


================================
Thanks all of you specially Suraj and Avizen.

Sometimes, along with the soluton, we require advice also.
Thanks Ganeshan for your valuable suggestion.
