Do you want to change security permissions in active directory? You can go oldskool and use dsacls, or you can go powershell! Examples below:


  1. Read all users information
  2. Create, delete and manage groups
  3. Modify the membership of a group

dsacls "OU=test,OU=tSFGroups,OU=tSF,DC=corp,DC=contoso,DC=com" /G corp\NHOLLIDA:grgwdtlccc



GR: Generic Read
GW: Generic Write
DT: Delete an object and all of its child objects.
LC: List the child objects of the object.
CC: Create a child object.
