php mssql_connect() without section name in freetds.conf

Hi,

anybody have any idea with the following ?

Does not work, gives 'Unknown host machine name'. Even with tds version = 7.0... 7.1, 8, etc..:

$link = mssql_connect("10.98.97.96:62220", 'user', 'pass');

Works because there is a section in freetds.conf named 'dasdswh':

$link = mssql_connect('dasdswh', 'user', 'pass');
