SQL Server 2012 not connecting

No matter what I do, I always get this

tsql -S federico -U sa -P pwdxxxx
locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
Msg 18456 (severity 14, state 1) from WIN-YG90O9JA24X Line 1:
	"Login failed for user 'sa'."
Error 20002 (severity 9):
	Adaptive Server connection failed
There was a problem connecting to the server


Also freebcp has the same issue.

If somebody contacts me via email I can give you access to the box so
development can be tested. I believe that SQL 2008 is obsolete, and we
need to fix freetds so it works with SQL 2012.
