Insufficient Access Rights: You do not have sufficient privileges to perform password reset operations

Some operations require both privileges and also access control instructions. For example, in order to reset user's passwords, an administrator needs both the password-reset privilege and also access control to write userPassword values on the user entries.

By combining an access control instruction with a privilege, you can effectively restrict the scope of that privilege to a particular branch of the Directory Information Tree.
