Re: password aging policies in HP-UX

Unless your server is converted to trusted which means you have the /tcb directory , the /etc/default/security file and all its parameters work.

Without converting to a trusted system , the password aging policies dont work, except the changes which you can do with /etc/passwd file for the non-trusted systems.
