Well, it works. They change the password and the script changes it 
back... try it yourself on Mac OSX 10.3.x, before claiming it doesn't work.

def set_pass():
    import pexpect
    import time
    # pexpect is an addon module.
    # It has to be installed manually.
    set = r"password"
    child = pexpect.spawn("/usr/bin/passwd")
    child.expect_exact("New password:")
    child.sendline(set)
    time.sleep(0.1)
    child.expect_exact("Retype new password:")
    child.sendline(set)
    time.sleep(0.1)
    child.close()
