I'd like to know what rights I need to give certain users so that they're
able to perform this in a specific OU

Create Users
Delete Users
Change Passwords

I've tried to make them a trustee of the OU but that doesn't work. The
only way it's working right now is that they're equivalent to admin and I
don't really want to keep it that way.

I'm running Netware 6.5 SP2. I'm using ConsoleOne 1.3.6e
