Linux Freetds ODBC

I am configuring a Linux server to connect to a MSSQL database using freetds and an ODBC driver setup.

I have all but completed this, but I am stuck with some mis-configuration that I cant figure out.

Here's the problem. I can connect the the mssql server using tsql, but I cannot connect to it using isql, which is what I need to get php to connect to it.

Here is applicable part of the freetds.conf file.

Code:

[TDS]
host = 10.10.64.102
port = 1433
tds version = 8.0
here's the odbc.ini. (This was setup using the linux GUI ODBCadmin tool).

Code:

[MSSQLServer]
Description = TDS
Driver = TDS
Servername = 10.10.64.102
Database = MyDb
UID = myuser
PWD = mypassword
Port = 1433
here are the commands I am using to connect:

Code:
#tsql -H 10.10.64.102 -p 1433 -U username -P password

#isql -v MSSQLServer username password

I can connect with the username and password using tsql, but not with isql or php.
