 In both cases once expiration happened it’s too late and nothing is done.
 The email is sent before expiration, with an alert delay which can be configured.
 
-### problems
-
 There may be some kind of conflict when people are using both shadowExpire, ppolicy and user-reminder.
 
+### 
+
+1. In posix mode we look for **shadowExpire** and compare it with the actual date to find if its expired. If not expired we sent an alter to the user if not already send
+ 
+2. In ppolicy mode we can only update pwdMaxAge in the policy, but if the policy is global it will change for all users.
+
+If we need different pwdMaxAge values in the policies, we need to look at the **pwdPolicySubentry** attribute for the user(s) who are going to be expired.
+
 ### solution
+
 In this case we may want to have an option to trigger user-reminder only on shadow expire or on ppolicy, or to send a different email depending on which expiration it happening.
