salt some base 64 encoding of 1002 paranoid md5 computations.
Even of the salt is based on the login, the point is that it is stored
separatly, so the system does not rely on the login string to check the
password.
The only other scheme which requires the user password somehow is the HTTP
digest authentification, and AFAIK no one in the world uses it;-)

Yes, I'm afraid there is no 'light' fix, other than acknowledging the
fact... Not a big issue.
