Role required: admin

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.
