title: Forms Authentication against Active Directory - LDAP Protocol
body: <p>I need to create a web page that authenticates users against an existing active directory. The domain is actually a cloud computing configuration where there is a domain controller and multiple other servers on the stack. </p>
  
  <p>I understand that objects from the System.DirectoryServices namespace can be used. However, I cant seem to path the code to the active directory through the LDAP://domain.com
  address. There doesnt seem to be any communication going on. I suspect there is some initial configuration necessary or security measures blocking the communication. </p>
  
  <p>I am working with this example from MSDN: <a href="http://msdn.microsoft.com/en-us/library/ms180890(v=vs.80).aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/ms180890(v=vs.80).aspx</a>.</p>
  
  <p>I get an error that says the server is not operational. </p>
