How to: Connect Using SQL Server Authentication,If Windows Authentication is not a practical option, see How to: Connect Using SQL Server Authentication.,The following points must be considered when you use Windows Authentication to connect to SQL Server:,Windows Authentication should be used to connect to SQL Server whenever possible for the following reasons:

The example assumes that SQL Server and the AdventureWorks database are installed on the local computer. All output is written to the browser when the example is run from the browser.

<?php  
/* Specify the server and connection string attributes. */  
$serverName = "(local)";  
$connectionInfo = array( "Database"=>"AdventureWorks");  
  
/* Connect using Windows Authentication. */  
$conn = sqlsrv_connect( $serverName, $connectionInfo);  
if( $conn === false )  
{  
     echo "Unable to connect.</br>";  
     die( print_r( sqlsrv_errors(), true));  
}  
  
/* Query SQL Server for the login of the user accessing the  
database. */  
$tsql = "SELECT CONVERT(varchar(32), SUSER_SNAME())";  
$stmt = sqlsrv_query( $conn, $tsql);  
if( $stmt === false )  
{  
     echo "Error in executing query.</br>";  
     die( print_r( sqlsrv_errors(), true));  
}  
  
/* Retrieve and display the results of the query. */  
$row = sqlsrv_fetch_array($stmt);  
echo "User login: ".$row[0]."</br>";  
  
/* Free statement and connection resources. */  
sqlsrv_free_stmt( $stmt);  
sqlsrv_close( $conn);

Using the SQLSRV driver of the Microsoft Drivers for PHP for SQL Server, the following example uses the Windows Authentication to connect to a local instance of SQL Server. After the connection has been established, the server is queried for the login of the user who is accessing the database.,Windows Authentication should be used to connect to SQL Server whenever possible for the following reasons:,The following points must be considered when you use Windows Authentication to connect to SQL Server:,By default, the Microsoft Drivers for PHP for SQL Server use Windows Authentication to connect to SQL Server. It is important to notice that in most scenarios, this means that the Web server's process identity or thread identity (if the Web server is using impersonation) is used to connect to the server, not an end-user's identity.

<?php
/* Specify the server and connection string attributes. */
$serverName = "(local)";
$connectionInfo = array( "Database"=>"AdventureWorks");

/* Connect using Windows Authentication. */
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false )
{
     echo "Unable to connect.</br>";
     die( print_r( sqlsrv_errors(), true));
}

/* Query SQL Server for the login of the user accessing the
database. */
$tsql = "SELECT CONVERT(varchar(32), SUSER_SNAME())";
$stmt = sqlsrv_query( $conn, $tsql);
if( $stmt === false )
{
     echo "Error in executing query.</br>";
     die( print_r( sqlsrv_errors(), true));
}

/* Retrieve and display the results of the query. */
$row = sqlsrv_fetch_array($stmt);
echo "User login: ".$row[0]."</br>";

/* Free statement and connection resources. */
sqlsrv_free_stmt( $stmt);
sqlsrv_close( $conn);

PHP uses the presence of an AuthType directive to determine whether external authentication is in effect. , Both Netscape Navigator and Internet Explorer will clear the local browser window's authentication cache for the realm upon receiving a server response of 401. This can effectively "log out" a user, forcing them to re-enter their username and password. Some people use this to "time out" logins, or provide a "log-out" button. , An example script fragment which would force client authentication on a page is as follows: , Note, however, that the above does not prevent someone who controls a non-authenticated URL from stealing passwords from authenticated URLs on the same server.

It is possible to use the header() function to send an "Authentication Required" message to the client browser causing it to pop up a Username/Password input window. Once the user has filled in a username and a password, the URL containing the PHP script will be called again with the predefined variables PHP_AUTH_USER, PHP_AUTH_PW, and AUTH_TYPE set to the user name, password and authentication type respectively. These predefined variables are found in the $_SERVER array. Only "Basic" and "Digest" authentication methods are supported. See the header() function for more information.

I'm working on an intranet web application in PHP. Im trying to use Windows NT login credentials to logon to the application. The trouble im having here is how do i get the remote users windows username? I want to obtain the username and then check against various LDAP groups so that I can direct them to appropriate pages in my application.,You have to send the NTLM-Authenticate headers first. After that, there should be the right user in the $_SERVER-Vars,Not sure if you still need help with this but recently i've had to create code to log intranet users on to our site automatically using windows authentication which is run using IIS. When using windows authentication and ISS in order obtain the logged in user firstly ensure you have windows authentication enabled and anonymous disabled. ,If you require more info let me know.

I've so far tried

< ? php
echo $_SERVER['REMOTE_USER'];
echo $_SERVER['PHP_AUTH_USER']; ?
