This document describes a problem encountered on the Identity Services Engine (ISE) where pages do not fully load when Adblock Plus is used, and it offers a solution to the problem. With the prevalence of advertisements on most websites, many users install Adblock Plus as an add-on to their browsers. If pages match a certain signature, Adblock does not allow the pages to load or the scripts to run.
The ISE uses a utilities file named adutils for many Active Directory functions within the administrative web interface. Adblock Plus does not allow the adutils script to be run on the page because it has been found to be called by advertisements on other web sites.
The adutils script on the ISE is not related to advertisements. It is a script that contains various Active Directory-related functions used in order to populate data related to Active Directory. This script is used on many pages in ISE not limited to the endpoints page, which includes many of the Active Directory configuration pages. Any Adblock software should be configured with ISE on the exception list so that it is disabled while ISE is administered. Even though the software will be disabled, ISE will not display advertisements.
