I was under the impression that Windows did not have to send the
authentication information if you use the username and password
arguments in mssql_connect().  I'm not having to do anything different
on my Linux box.

My options at the moment are a bit limited; AD and Kerberos are not in
my available list of authentication mediums.  Also, just to verify, I am
using Apache 2 on both the internal Linux box and the external Windows
box.  IIS is fortunately (or unfortunately depending on your point of
view) not part of the equation.

I've been using SQL authentication.  Using Windows authentication was
time prohibitive even during development internally, so we made sure we
setup the server with mixed mode.  It works just fine this way when
connecting from the Linux box on the internal network.

I'm unfamiliar with this kind of connection string.  This is how I

$sqlConnect = mssql_connect($sqlHost, $sqlUser, $sqlPass) or die("Could
not connect to database: ".mssql_get_last_message());

I've even tried 'sa', no luck.
