Matias,  

Sybase servers use TDS 5.0.  The login packet for TDS 5.0 provides up to 30
bytes for the password.  Cf. http://www.freetds.org/tds.html.  AFAIK, the
30-byte limit is a fixed property of the protocol.  

If you're willing and able to use tcpdump(8) to capture a login packet with
a password longer than 30 bytes, I'm sure folks here would be interested to
see it.  

Could it be perhaps that isql lets you enter a longer password but ignores
the characters beyond 30?
