Self service portal questions

I downloaded the demo of ADM+ to try out, but I am a bit confused about the self-service portal feature. When logged in as a basic user in the online demo (4.0), I see the options for unlocking a co-worker's account and specifying which employees are allowed to unlock your own account. I do not see those in the copy I downloaded to run in my test network (4.1), and cannot figure out how to enable them.

Also, if I can get that functionality, I see in the online demo that it appears that the end users can specify which other users are allowed to unlock their account for them. Is there any way to disable their ability to do so, and instead let the admins dictate who can unlock their accounts?
