PHP script Example

Below is basic PHP script which demonstrates MySQL and Active Directory communication :

";
mysql_close($dblink);


/* Going a step forward now we will connect to ldap server */
$ldapserver = "xxxx";

$user = "cn=Ashish Srivastava,cn=Users,dc=mydomamin,dc=com";
$passwd = "ashish";
$base = "cn=Users,dc=mydomamin,dc=com";


// Connect to ldap server
$dsCon = ldap_connect($ldapserver);


// Make sure we connected
if (!($dsCon))
{

print("Sorry, cannot contact LDAP server");
exit(2);

}


// Set Active Directory Specific Options
ldap_set_option($dsCon,LDAP_OPT_REFERRALS, 0);


// Bind LDAP
$bindresult = ldap_bind($dsCon,$user,$passwd);

if(!$bindresult){
$errno = ldap_errno($dsCon);
$error = ldap_error($dsCon);

print "LDAP Error ($errno): $error";
exit(3);
}


// Now Perform Search
$attributes = array("cn"); // attributes which you want

$search_filter = "(&(objectclass=user)(objectcategory=user)(sAMAccountName=ashish.srivastava))";
$search_result=ldap_search($dsCon, $base, $search_filter, $attributes);
if(!$search_result){
$errno = ldap_errno($dsCon);
$error = ldap_error($dsCon);

print "LDAP Error ($errno): $error";
exit(4);
}


// Getting Entries
$entry = ldap_get_entries($dsCon,$search_result);

if(!$entry){
$errno = ldap_errno($dsCon);
$error = ldap_error($dsCon);

print "LDAP Error ($errno): $error";
exit(4);
}


$cn = $entry[0]["cn"][0];
//var_dump($entry);
print "Common Name: $cn
";
ldap_close($dsCon);
?>

Custom HTTP Modules

Custom HTTP Modules

HTTP Modules provides an opportunity to examine each incoming and outgoing request before request processing.
A typical use of HTTP module is URL rewriting on the basis of content of URL string. For example if i want to convert URL like "mywebproject/ashish/default.aspx" into "mywebproject/default.aspx?user=ashish" or vice-versa.

Creating custom HTTP Modules:

• Make a class for implementing your custom module and implement IHttpModule Interface.
• Add event handlers for BeginRequest and EndRequest events
• Register your custom HTTP Module using web.config

Make a class and adding Event Handlers:

 public class UrlMapperModule : IHttpModule
{
private EventHandler onBeginRequest;

public UrlMapperModule()
{
onBeginRequest = new EventHandler(this.HandleBeginRequest);
}

void IHttpModule.Dispose()
{
}

void IHttpModule.Init(HttpApplication context)
{
context.BeginRequest += onBeginRequest;
}


private void HandleBeginRequest( object sender, EventArgs evargs )
{
// Now check every request
                        string requestUrl = app.Context.Request.Url.PathAndQuery;
           }
      }

Registering Custom HTTP Module in web.config:
