Подключение к базе данных MSSQL (PDO, FreeTDS, ODBC)

У меня есть сервер Ubuntu 12.04, и я пытаюсь установить соединение с базой данных MSSQL.

Мне удалось подключиться с помощью tsql и isql, но osql не работает, и соединение с PHP с использованием PDO также не работает .. Я постараюсь предоставить как можно больше информации, и если вам нужно больше, просто дайте мне знать, и я отредактирую.

freetds.conf:

[MSSQL]
  host = TPSACC
  port = 54488
  tds version = 8.0

odbc.ini:

[MSSQL]
Description     = MS SQL connection to PRODUCTION database
Driver          = FreeTDS
Database        = PRODUCTION
Server          = TPSACC
UserName        = sa
Password        = pass
Trace           = No
TDS_Version     = 8.0
Port            = 54488

odbcinst.ini:

[FreeTDS]
Description = ODBC for Microsoft SQL
Driver      = /usr/local/lib/libtdsodbc.so
UsageCount  = 1
Threading   = 2

В PHP у меня есть:

$conn = new PDO ("dblib:host=TPSACC;dbname=PRODUCTION","$username","$pw");

..или..

$conn = new PDO ("dblib:host=TPSACC;port=54488;dbname=PRODUCTION","$username","$pw");

И они оба возвращают эту ошибку:

SQLSTATE[HY000] Unable to connect: Adaptive Server is unavailable or does not exist (severity 9) 

Я застрял здесь на пару дней и не могу понять, почему на самом деле работает только половина соединений ...

Любая помощь очень ценится, спасибо!
