Status: Bogus
Bug Type: MSSQL related
Operating System: win2003
PHP Version: 4.3.9
New Comment:
"Please test the connection with mssql client tools first." This was
the first initial test and authentication through Enterprise Manager or
QA is fine.
"Connecting to mssql servers requires that the ports uses is open in
the
firewall" There are no FW in use as this is a purely an internal
connection.
"that the correct user id and password is used" User and password have
already been confirmed as correct.
"If
Integrated NT authentication is used you must specify
mssql.secure_connection = On in your php.ini file." The sql servers
use Mixed mode authentication with the connection string requiring the
sql login user and password, which are correct.
This was clear from the fact that web server A could not connect to sql
server B, however, using the same script a connection is possible from
web server b to sql server b. If the username or password was
incorrect, no connection would be possible, from anywhere.
Basically is there a problem when trying to connect to an SQL server
with mssql_connect when the web server is in a different non trusted
domain to the sql server?

Please test the connection with mssql client tools first.
Connecting to mssql servers requires that the ports uses is open in the
firewall, that the correct user id and password is used (if the SQL
server allows SQL server authentication) or that the user account used
to execute the PHP script is authneticated on the web server. If
Integrated NT authentication is used you must specify
mssql.secure_connection = On in your php.ini file.

Description:
------------
Webserver A is in an active directory VHOSTS, webserver B is in Active
directory VHOSTS2. MSSQL Server A is in VHOSTS and MSSQL Server B is
in VHOSTS2. If an attempt is made to connect to MSSQL Server A from
Webserver B using mssql_connect the connection fails. However, if an
attempt is made to connect to MSSQL Server B from Webserver B using
mssql_connect, the connection will succeed. This also applies if you
change the test around so webserver A connecting to MSSQL Server B.
This is purely an internal connection with the only difference in the
webservers and ms sql servers is being they're in different domains.
Reproduce code:
---------------
<?php
db_connect();
?>
<?php
function db_connect ()
{
$db = mssql_connect ("sql2k230", "*****", "******");
if (!$db) {
echo "\nError connecting to SQL Server, User = '" . "" . "', p/w =
'" . "" . "' \n\n";
die('Could not connect to server: ' . mssql_get_last_message());
}
$result = mssql_select_db ('master', $db);
if (!$result) {
die('Could not select database: ' . mssql_get_last_message());
}
}
?>
Expected result:
----------------
The script above should have html included, in which case whatever html
is included should be produced in the browser after the db connect has
taken place. Or a blank page if using the code only.
Actual result:
--------------
Warning: mssql_connect(): Unable to connect to server: sql2k227 in
e:\******** on line 28
Error connecting to SQL Server, User = '*****', p/w = '****' Could not
connect to server:
