sorry to repost the question again , but i really still can't fix the problem ,

I use the below command to force user to change the password ,

# chage -d0 user1
# chage -d0 user2

however , there is the below problem :
when the user1 is login and hold the screen :

login: user1
Password:
You are required to change your password immediately (root enforced)
Changing password for user1
(current) UNIX password:

if the user1 is not change the password promptly and stop at the above the screen , then when user2 login to the system , it will stop at the below screen :

login: user2
Password:
You are required to change your password immediately (root enforced)

user2 will hold at the above screen until user1 exit the change password screen , this problem will also happen other RH system , can anyone kindly help to suggest the solution ? Thank in advance.

I am not sure why this happen , but I also found that if user1 stop at the screen , then root can't use the command chage

# chage -d0 user3
chage: can't lock password file

can I fix the problem if I can unlock the password file ? thx

The user does have a file lock on passwd. You should be able to find the process holding the lock using lsof. Afterwards an appropriate kill can take care of it.
