请教下freetds连接MSSQL出错的问题

这是安装步骤:
./configure --prefix=/usr/local/freetds --with-tdsver=7.2 --enable-msdblib
make ; make install

这是测试的报错:
[root@IP etc]# /usr/local/freetds/bin/tsql -H 192.168.1.2 -p 1433 -U admin
locale is "C"
locale charset is "ANSI_X3.4-1968"
Password:
Msg 20017, Level 9, State -1, Server OpenClient, Line -1
Unexpected EOF from the server
Msg 20002, Level 9, State -1, Server OpenClient, Line -1
Adaptive Server connection failed
There was a problem connecting to the server



但不知道是哪里出了问题~

用户名参数是小写u，不是大写u，
