I've noticed a bunch of questions from folks confused about how the new domain administrators work and the whole delegated privs model works. Having figured it out for myself, I figured I'd put together a wiki page.
Right now for some reason the zimbra wiki page only randomly loads the attached pictures so I'm going to link the wiki version and a version in my Zimbra notebook. If a zimbra wiki expert want to help me out here, I'd appreciate it.
I hope this helps someone:
