mssql_connect(): Unable to connect to server (without freetds.conf)

Question

I have 2 servers: one is OpenSUSE, another one is SLES 11 sp2 Suse Linux Enterprise Server.

In order to have connection to MSSQL I have to install mssql.so for php.

OpenSUSE permits to install mssql from rpm. SLES - does not have mssql rpm, and this is why need to compile it.

OpenSUSE: mssql rpm installed =>

$server="172.x.x.x:49888";
$username="username";
$password="password";
$link = mssql_connect($server, $username, $password);

here successfully connected to MSSQL!

SLES: with mssql.so compiled =>

$server="172.x.x.x:49888";
$username="username";
$password="password";
$link = mssql_connect($server, $username, $password);

error: Warning: mssql_connect(): Unable to connect to server: 172.x.x.x:49888

and if I edit freetds.conf

#A typical Microsoft server
[Dovico]
    host = 172.x.x.x
    port = 49888
    tds version = 7.0

and change php like this:

$server="Dovico";
$username="username";
$password="password";
$link = mssql_connect($server, $username, $password);

=> successfully connected to MSSQL!

So my question is how can I have MSSQL connection on SLES (with mssql.so compiled) using this

mssql_connect("172.x.x.x:49888", "username", "password");

and not using freetds.conf ?

Solution

Edit freetds.conf (uncomment and change version):

from

[global]
        # TDS protocol version
;   tds version = 4.2

to

[global]
        # TDS protocol version
    tds version = 7.0

and restart Apache.
