copying user password to another machine

["Reuben D. Budiardja" <techlist voyager phys utk edu>]

Hi all,
Got a quick question.

I have a user in a RHEL 3 WS. I want to give him access to another machine 
running RH 9 and want to let him use the same password he uses for the RHEL 
machine. But I don't know / don't remember his current password. Can I just 
copy the line that contains his username in /etc/shadow in RHEL 3 machine, 
and stick it to the /etc/shadow file in the second machine (RH 9) ? anything 
else?

Thanks.
RDB
