You're not clear here on whether you already have a cron job for this,
whether you are attempting to write one.

As far as I can see, no, the only way is to interpret the state values
in the 
DN along with the applicable password policy.

I have implemented as follows:

1)A script that can operate either as command-line passwd replacement,
or CGI, 
which allows the user to check their password and be prompted to change
it if 
it has expired, as well as handling any ppolicy errors during password

2)A perl script to search the directory for DN's whose passwords are
about to 
expire, sending them a mail notifying them when the password will
expire, with 
a link to the URL where (1) runs as a CGI

3)A script for the admin to unlock accounts that have been locked out,
their password, and send them a notification.

I would like to merge (2) and (3), but I was in quite a hurry to get
working as I had a number of users who were locked out at the time.

The scripts (1) and (2) in their present state are available at 
http://staff.telkomsa.net/~bgmilne/ldap/ . I am still trying to resolve
one or 
two issues, but they should be of use to you.

If (3) would be useful to you, I will make that available as (or, an
(2) which has the functionality).
