About this task

One method is to track the active status of AD users and create a business rule to update corresponding accounts when an AD account is inactive.

Procedure

1. Create a new string field on the User [sys_user] table to track the value of the AD userAccountControl field.

   For example: u_ad_user_account.

2. Create an LDAP transform script to set the field value.

   target.u_ad_user_account = source.userAccountControl
   

3. Update the LDAP filter to show disabled AD accounts.

   Here is an example of a filter.

   (&(objectClass=person)(sn=*)(!(objectClass=computer))(!(userAccountControl:1.2.840.113556.1.4.803:=2)))
   

   Here is an example of a replacement filter you can use.

   (&(objectClass=person)(sn=*)(!(objectClass=computer)))
   

4. Create an onChange business rule to set the active field to false whenever the u_ad_user_account field has the value 514.

   '514' indicates an inactive account.
