[389-users] notify users before delete them

Hello, We have recently setup a new 389 directory server. One of our problems  is to maintain user's accounts.  Once we find proposed accounts for deletion i.e user has retired etc, we want to sent him an email, inform him that his account will be inactive in 30 days. Once 30 days are  gone, then the account  is disabled, for another 30 days and then removed. Are there any plugins that can help us to achieve the above scenario, whole or partially? Thank you in advance Maria -- **
