Well, as you already said the username in the Authentication is not
enough when handling multidomain. Most probably, the proxy needs to
set a realm in the 401/407 and in case of a multidomain environment it
depends on the From domain.
If From is "anoymous" then PPI header could be inspected to extract
the user domain and generates the nonce with the proper realm.
