This command* is incorrect as far as I have seen on my 11.3i system.

*

/usr/lbin/modprpw -m exptm=0 root

You want 

/usr/lbin/modprpw -m exptm=-1 root

check by issuing

passwd -s root

pre and post issuing the above command.  The first command expires your password on the day you issue the command.   -KJ
