I can not do portal.login('john', None, ILocalHomeFolder) since at log
in time I don't know if john is an os or application account... The
credential checker will find out what kind of account is John.

Later I would like to extract the provider from the AvatatID and doing
(user, provider) = AvatarID.split('@', 2) is a bit more complicated
and error prone.
