Detailed Description:
the FEU v.2.12.7 new install sets:
password to be c(64)
but update doesn't change the current c(32)
after the password is salted it is to short and never matches.
therefore login fails
version 2.13
new install sets password to c(128)
and again no change in update.
2.13 is not backwards compatible
it requires salt value in db
forcing confirmation or change of password doesn't create salt value in db.
those users cannot login.
