Amit,
Can you check to make sure you are using MD5? You can find out if you are using MD5 cipher by looking at the encoded password string in your /etc/shadow file. If it starts with $1$ and is 34 characters long, then it is an MD5-based format. DES format is shorter, it is only 13 characters long. MD5 is default, but may have been changed during install etc.

Also, are these users being authenticated locally or by LDAP? If it's LDAP, then you will have to talk to your LDAP admin.

Other than that I'm out of ideas.....

NAME
yppasswd - change password in Network Information Service (NIS) SYNOPSIS
yppasswd [name] DESCRIPTION
Note If Enhanced Security is enabled on your system, use the passwd command to change your password, even if NIS is in use. The yppasswd command lets you change your password in the Network Information Service (NIS) map, a network data base service. Only you or the superuser can change your NIS password. When you enter the yppasswd command, the program prompts you for the old password and then for the new password. Note that the passwords are not displayed on the screen. Next, the program asks you for the new password again, to verify that you have typed it correctly. If you do not type the passwords cor- rectly, you will receive an error message after you enter the new password. Your new NIS password must meet one of the following requirements: It must be a combination of at least six alphanumeric characters, or It must be a minimum of four characters, with at least one being non-alphanumeric, such as a control sequence. Note The passwd command does not change the NIS password. This command only changes the local password file (/etc/passwd), and not the NIS mas- ter password file. ERRORS
Your new password does not meet the minimum length requirement. You misspelled your new password or its verification. Your new password can not be activated. It must be different from your old password and your login name. FILES
