freetds和pyodbc无法连接

我目前正在设置从Linux机箱到Microsoft SQL服务器的连接.我在Linux机器上安装了FreeTDS和pyodbc.

我已经设置了以下文件:/etc/freetds/freetds.conf

[sqlserver]
    host = 
    port = 1433
    tds version = 8.0
    client charset = UTF-8

〜/ .odbc.ini的

[sqlserver]
Description     = FreeTDS MSSQL
Driver          = FreeTDS
Servername      =  
Database        = Reports
TDS_Version     = 8.0

/etc/odbcinst.ini

[FreeTDS]
Description             = FreeTDS MSSQL
Driver                  = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so
Driver64                = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so
Setup                   = /usr/lib/x86_64-linux-gnu/odbc/libtdsS.so
Setup64                 = /usr/lib/x86_64-linux-gnu/odbc/libtdsS.so
UsageCount              = 1
CPTimeout               = 
CPTimeToLive            = 
DisableGetFunctions     = 
DontDLCLose             = 
ExFetchMapping          = 
Threading               = 
FakeUnicode             = 
IconvEncoding           = 
Trace                   = 
TraceFile               = 
TraceLibrary            = 

当我尝试运行tsql -S sqlserver -U username -P密码时,出现以下错误:

locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
Msg 18452 (severity 14, state 1) from SYMPLECTIC03 Line 1:
    "Login failed. The login is from an untrusted domain and cannot be used with Windows authentication."
Error 20002 (severity 9):
    Adaptive Server connection failed
There was a problem connecting to the server

我也尝试用pyodbc连接,在下面的脚本中:

import pyodbc
try:
    cnxn = pyodbc.connect('DRIVER=FreeTDS;SERVER=same_ip_as_above;DATABASE=Reports;UID=myusername;PWD=mypassword')
except pyodbc.Error, err:
    print err

这会打印以下错误:

('001', '[001] [nxDC[reD]SLSre]nbet onc odt ore (0) (SQLDriverConnect)')

不完全是最有用的错误消息.

尝试连接时有什么问题吗？

作为旁注,我们的数据库需要Windows身份验证,而不是集成.我可以telnet连接到主机,所以这也不是问题.
