Ldap authentication in ASP.Net MVC 3 - asp.net

Question

I´m trying to authenticate users in ASP .Net MVC with ldap, but it isn´t working. I´m running wireshark to see if IIS is at least connecting to the LDAP server, but it´s not connecting.
I have an SQL database for the web, and then I want to authenticate users with a LDAP server.
Here is my Web.config:
<configuration>
<connectionStrings>
<add name="ADConnectionString" connectionString="LDAP://IP:PORT/OU=...,DC=..."/>
<add name="MySqlMembershipConnection"
connectionString="Pipe=MySQL;
Protocol=pipe;
Server=localhost;
Database=My DB;
User Id=My User;
Password=My Password;
"
providerName="MySql.Data.MySqlClient"/>
</connectionStrings>
<appSettings>
<add key="webpages:Version" value="1.0.0.0" />
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>
