Hey all, Our OpenLDAP environment is up and functional and is working great. I was asked if there is a way to have the server email users when their account password is about to expire. For instance, 7 days before expiration they get an email that lets them know their password will expire on date x. Is there functionality within OpenLDAP to do this, or has anyone written a script that would do it? We are using the policy overlay to enforce the password policy.

You have to write an external script which searches for (pwdChangedTime<=x) with x calculated from current time and password expiration time.
Ciao, Michael.

as far as I know there is nothing to do this. So we wrote a script in Perl (but can be write in other langages "supported" libldap). The most difficult thing is to ask the timestamp of the last change, to add the delay of change enforcement and write the mail to the address in the ldap if you have. Put it in crontab. Forget it ;-) I recommend to have a specific user for this type of traitement with appropriate acl.

Sorry for my bad english, for not provide this script that is not my own. Be free to ask again if you have trouble.
Here's how we did it, in broad terms - we're using password policy (ppolicy) too.
We query LDAP for pwdMaxAge for password policy we're addressing (this is in seconds). Then we subtract two weeks from it (for two weeks' worth of warning - our script runs once a week) ... and then capture the date/time that many seconds ago (for easy comparing when looping through accounts) ... in the same format the pwdChangedTime (and createTimestamp) are stored in.
Example of above in bash (vars LDAPSEARCH, LDAPBIND, Policy being set previously): pwdMaxAge=$($LDAPSEARCH $LDAPBIND -b $Policy pwdMaxAge -LLL | grep ^pwdMaxAge | awk '{print $2}') twoweeks=$((14*24*60*60)) pwdWarnAgeSeconds=$((pwdMaxAge-$twoweeks)) pwdCompareAge=$(date -d "$pwdWarnAgeSeconds seconds ago" +%Y%m%d000000)
Of course, that be one-lined, but obfuscated code is lame - especially in a work environment. pwdCompareAge=$(date -d "$(($($LDAPSEARCH $LDAPBIND -b $Policy pwdMaxAge -LLL | grep ^pwdMaxAge | awk '{print $2}')- $((14*24*60*60)))) seconds ago" +%Y%m%d000000) (That's probably broken somewhere... blech).
We then search for accounts using the password policy we're addressing, and parse those accounts where pwdChangedTime (or, if it's missing, createTimestamp) is less than pwdCompareAge (set above), and send them an email with instructions on how to change the password.
That's how we did it at least. Good luck!
