How to Configure Form Base Authentication(FBA) in SharePoint Server 2010 Claim based using LDAP


Hello Friends,

It’s been months I haven’t written anything as I was busy with lot of stuff. There are many things to write but starting with topic for which I got many mails from lot of friends through blogs and linked in.

As we all are aware with Claim based in SharePoint 2010 and different option/ways of Authentication( Ldap, Sql, Federation). Claim is the technology of today, In SharePoint 13 Microsoft even removed the Classic  Mode and made it the days of past. Today we will discuss with the form based with LDAP Authentication.

 I will try to provide and exact way to configure Form based authentication in Claim Based Authentication in SharePoint. To enable a form based , web application should be created in Claim based mode only.


Creating a Claims based web application using GUI

  • Go to Application Management in Central admin
  • Go to Manage Web Applications and create a new web application
  • In the option select Claims Based Authentication mode

  • In claim authentication types select Enable Windows Authentication and select NTLM
  • In authentication type section for  form based configuring select Enable ASP.NET Membership provider name.

    Note: Membership provider and Role manager name which you provide in this section will be used in everywhere for web config and enabling it. So give it properly and note it for reference.

  • Click on “OK” button to create the web application.

  • Go to CA, Application Management, Create site collections
  • Select the appropriate web application
  • Create a site collection with adding appropriate entries .
  • Now the task remain is to modify different web config files and adding user policy for the web application.
