Thanks for the response, Yes I have created the user helpdesk. I also tried by deleting the user 'helpdesk' and then recreated it. user's login shell is bin/bash, group is 'helpdesk' and its home directory is /home/helpdesk

cat /etc/passwd|grep helpdesk
helpdesk:x:572:572::/home/helpdesk:/bin/bash

cat /etc/passwd-|grep helpdesk
helpdesk:x:572:572::/home/helpdesk:/bin/bash

cat /etc/shadow|grep helpdesk
helpdesk:$1$Encrypttext$Encrypttext/Encrypttext.:17761:0:99999:7:::

cat /etc/shadow-|grep helpdesk
helpdesk:$1$Encrypttext$Encrypttext/Encrypttext.:17761:0:99999:7:::

cat /etc/group|grep helpdesk
helpdesk:x:572:

cat /etc/group-|grep helpdesk
helpdesk:x:572:

exaclty you forgot to check
Code:
ls /home
using adduser and deluser to create your users, as adduser creates the home dir without further prompting, whereas useradd does not. if it is not there then try installing it.

Sorry for the late reply. Yes there is a directory in /home/ named helpdesk with the permission 700.

I have bolded a line in what you posted for emphasis. That isn't a typical message you'd see...unless the account was created in Active Directory/LDAP. Either the account exists in multiple locations (local *AND* AD/LDAP), or there is some sort of lock on the account on the authentication server.

What version/distro of Linux are you using, what authentication methods, and how was this user created initially?

This user was created as squirrelmail mail user. I am using Linux 5.11. I am able to change all others users account password except this one. So I deleted it using administration>'users and groups' gui utility.

Ok...then you don't have a SYSTEM user (which is what the passwd utility addresses), but a Squirrelmail user. Use Squirrelmail to change the password.

No luck.. I am not able to change squirrelmail password for this account also. Always saying incorrect user or password.

Thumbs up

I got this. helpdesk is a Active Directory user which was locked due to multiple login attempts using wrong passwords. I reset the password in AD and tried same password to login. Fortunately I am now able to login into squirrelmail.

Thank you all for your solution and support. Cheers!

Yep...and I mentioned AD/LDAP in post #8 as well. We were both ignored.
