Hi everybody, i need a help from u guy(s).
;;;;;;
1)created a user account by '/usr/sbin/useradd amartya'
2)Not Given any password for it.
3)After that i delete the account by '/usr/sbin/userdel amartya'
4)Simultaneously deleted the home directory,deleted the column in /etc/passwd, /etc/shadow, /etc/groups,/etc/gshadow
5)Problem comes after that.
When i am going to create the same user 'amartya' through the same above procedure & logging in that user (as su - amartya) &going to give password , then it is asking for current password.
But i am not having any password for it.
How can i over come from this problem
Please help me out ....

Not enough info-you don't even list what distro you have/use.

well, passwd doesn't care about passwords when it's run as root, so doing this as root should work-around the problem:
