Simple OU Membership Test

Author: Zinthose (talk, contrib)

About

This is a very basic OU testing macro intended for use in companies that use nsis to repackage software. This has been successuly tested on Windows XP and Windows XP x64 but should work fine on Windows 2000 and newer.

Example

/*  Don't forget to add these!
    --------------------------
      !include "LogicLib.nsh"
      !include "WordFunc.nsh"
    --------------------------*/
Section IsOUMember_Example
 
    ${If} ${IsOUMember} "Cool People"
        MessageBox MB_OK 'System is in the Cool People OU!'
    ${Else}
        MessageBox MB_OK 'Ah, the system is not cool enough.  Sorry.'
    ${EndIf} 
 
SectionEnd
