In HTTP this usually results in a 401 Unauthorized, asking the requestor
to identify himself..

Thats usually a 401 (identity not trusted, please supply another) or 403
(I know you but do not want to speak to you).

In the response entity or headers you MAY provide additional
information, such as the location of the public profile, just as you MAY
on any response.

I think it in this case can be assumed the requestor already knows the
public profile, no need to redirect back there, and such redirections
only risk resulting in some implementations entering a loop..
