I've been searching and have not found an answer to this. I am writing an application to automate the create of Distribution Groups at my company. I can create the list with realative easy, but I am having problems assigning security to it. I can set the manager easily enough with the "managedBy" attribute, but making it so the manager can do something (in ADUC I would just check the little box that says 'Manager can update membership list') to the list rather than just be a contact name... I'm lost. I realize it has to do with DACL and ACE's, but I just couldnt find a good source for this.
