Sharepoint 2010 Form Based Authentication Using Active Directory

In this article I will try to show how we can use Active Directory Form Based Authentication in Sharepoint 2010 using Lightweight Directory Access Protocol (LDAP)

1.       Add Connection string and membership provider in Central Administration web.config









NOTE: connectionString will differ based on domain configuration. Please contact you Administrator to provide the LDAP details.

2.       Add Connection string and membership provider in SecurityTokenServiceApplication web.config







NOTE: connectionString will differ based on domain configuration. Please contact you Administrator to provide the LDAP details.

3.       Create a new site with claim based authentication using Central Administration



Authentication : Claim Based

Claims Authentication Types: Enable Windows Authentication -> Integrated Windows authentication - > NTLM

Leave others to default

4.       Now Create Site Collection at port 2233



And add Primary / Secondary Site Collection Administrators





So the resultant site will look like below.

5         Extend the web application to port 3322 and enable form based authentication (FBA)



Set the public URL Zone- Intranet or Extranet

5.       Add Users to the Intranet zone using User Policy









Add more users as required with desired permissions.
Now open the newly extended application, and use your domain credentials to login the app.
