Hi Antgiant, thanks a lot for your reply.

Seems that bakery module works only with subdomain that are on the same
second-level domain, that is not my case... :/

Ideally, i need a solution also to synchronize profile fields (it's not a
strict requirement).

The situation is really complicated because "username" are not unique across
different sites, so probably "foobar" user of "site a" is not the same
"foobar" of site b.

I think that OpenID solution would be better, but all subsites must be in
the same time provider/producer, example:

1) I have an account on site a
2) I log in with my openid account of site-a to site-b
3) site-b asking me if i'm a new user or i already have an account to
site-b, if new site will grab data from site-a to create my new account
otherwise it synchronize with site-b account.
