Current version supports only one organizational unit path. We'll add your request for supporting several paths to roadmap.
Your filter example is for filtering inactive accounts. In the web part there is an option "Display inactive users" (together with active ones). However we'll add option for scripting filtering to road map too.
goetz kober
like your web app but
filtering the ad is not flexible enough. If I understand right there is only one filter path possible in the webpart:
Type in the directory path to the Organizational Unit containing the users you want to display in the Web Part
Examples:
(&(objectCategory=Person)(objectClass=User)(sn=*)(!userAccountControl:1.2.840.113556.1.4.803:=2)) (&(objectCategory=Person)(objectClass=User)(sn=*))
