I can't seem to fetch the verifiedEmail field when trying to login to AOLs OpenID on my site. Every other provider that I know of provides this property, but not AOL.
I realize that AOL somehow uses an old OpenID version, although is it feasible to just assume that their e-mail ends in @aol.com? I'm using the RPXNow library with Python.
I believe that OpenID lets the user decide how much information to "share" during the login process.  I can't say that I am an expert on the subject, but I know that my identity at myopenid.com lets me specify precisely what information to make available.
Is it possible that the AOL default is to share nothing?  If this is the case, then you may want to do an email authorization directly with the user if the OpenID provider doesn't seem to have the information.  OpenID doesn't mandate that this information is available so I would assume that you will have to handle the case of it not being there in application code.
