Shalom,

The root password has already expired.

To fix this, null it out first.

vi /tcb/files/auth/r/root

Change the line that looks like:
:u_pwd=AjDIB7xoAZVGE:\

to
:u_pwd=:\

Save it.

Quickly run the passwd command and set the root password.

Even better, take the machine to single user mode so there is no chance of anyone getting root priviledges.

Try using the /sbin/passwd command to change the password. My understanding is /sbin/passwd will bypass all the checks.

To know if you are in trusted mode.
If you have the /tcb directory and the subdirectories under it. And, you have the /usr/lbin/modprpw command. (This is an arbitrary command selection. There will be several other 'trusted system' commands in the /usr/lbin directory.)

The encrypted passwd on a trusted stsem is stored in the /tcb/files/auth/r/root

If not trusted, look into the /etc/passwd

For trusted mode - if the /tcb directory exists, the system probably is in trusted mode.

If it is in trusted mode you can try issuing the following command against root to reset the password paramemters

/usr/lbin/modprpw -k root
