Sol 8 - Pam prompts for old root password

When changing root's password as root, system prompts for old root password. I just got assigned a batch of servers, and this is the only server that does this.

hostname <root>:/# passwd root

Password:

It should, like the other systems,

# passwd root

New password:

I suppose you have done which passwd and it pointing to the right one.Also is this trusted solaris?

No this is not "Trusted Solaris OS." Comparing its sister server and both have passwd points to '/usr/bin/passwd'This problem is similar but mine is with Solaris 8 not Solaris9 example in:

pam_krb5's password management should not be prompting for old or for new passwords

/etc/pam.conf was missing the following line:passwd auth required pam_passwd_auth.so.1
