What is wrong with my claims-based configuration?

Hi I did whatever i had to do with this article:

http://sharepointchick.com/archive/2010/05/06/configuring-claims-and-forms-based-authentication-for-use-with-an.aspx

But unfortunately, It is not working. What I guess is that maybe I am not providing correct data in the text below:

<membership>
   <providers>
      <add name="LdapMember" 
         type="Microsoft.Office.Server.Security.LdapMembershipProvider,
 Microsoft.Office.Server, Version=14.0.0.0, Culture=neutral, 
         PublicKeyToken=71e9bce111e9429c" 
         server="ham.com" 
         port="389" 
         useSSL="false" 
         userDNAttribute="distinguishedName" 
         userNameAttribute="sAMAccountName" 
         userContainer="OU=floor1-2,DC=ham,DC=com" 
         userObjectClass="person" 
         userFilter="(ObjectClass=person)" 
         scope="Subtree" 
         otherRequiredUserAttributes="sn,givenname,cn" />
   </providers>
</membership>

I have just changed the server attribute,OU and DC is that enough?

thanks.
