[tpm] changing password for multiple accounts

Thank you for the reply.

I was wondering using some of the utilities provided by HP UX in /usr/lbin
i.e. modprpw and getprpw in Perl to do the following:
1 - Get expiry date by following command
 /usr/lbin/getprpw -m spwchg userid
which will return a string as follow:
 userid = Tue Aug 19 08:27:50 2008
my intention is to get this date and convert it to epoch and get current
epoch date and get the difference. If the difference is more than 83 days
then the script issue a warning screen.

2 - if a user account is disabled then enabled it with
modprpw -x userid
and reset the password using
moprpw -x userid

As for LDAP I am doing a quick tutorial but it is mostly theory, So if you
can please give me a reference to web site where it hsow step by step
procedure to do password synch on trusted system.

Also I need to know if LDAP is able to synch the password with windows

Thank you again for reply.
