Configuring Form Based Authentication (FBA) in SharePoint 2010

Introduction

This article explains step by step procedure to enable form based authentication (FBA) in SharePoint 2010.

I also written article on enabling form based authentication (FBA) in MOSS 2007 in code project site & blogger site and is available here [Code Project : “http://www.codeproject.com/Articles/19055/Form-Authentication-for-MOSS-2007-Site”, Blogger Site : “http://nagendra-gunaga.blogspot.in/2012/03/form-based-authentication-fba-for-moss.html”]

Setting up ASP.Net 2.0 Forms Authentication User and Role Data Source

This section explains creation of database which is used to store user's information such as credentials and roles which is used for Form Authentication. This section also explains the configuration of Membership and Role providers in the web.config file and creation of users using ASP.Net configuration wizard. This article shows creating a user and which will be used for testing Form Authentication later.

Create Database

To create database, Microsoft has provided a tool/ utility called aspnet_regsql.exe that creates a database for us. This utility can be found in %windir%\Microsoft.Net\Framework64\v2.0.50727 folder. Please see the image below:

Executing aspnet_regsql.exe file will open ASP.Net SQL Setup wizard that will walk through creating the ASP.Net database. I have added the database name as FBANetDB and configured it for windows authentication. Please see the image below:

Click on Next button. Please see the image below:

Select Configure SQL Server for application services option and click Next button. Please see the image below:

Click Next button. Now the database FBANetDB is created successfully. Please see the image below:

Configure Membership and Role Providers

In the previous section, database is created successfully. Now we need to add a user in to database. Using ASP.Net Configuration Wizard, users can be added the database. This can be achieved by creating web site that will allow us to add the users and roles and also ensure the database connection strings, membership and role providers are correctly configured before we bring SharePoint in to equation.

Below steps explains creating web site and configuring membership and role providers and executing ASP.Net Configuration Wizard.

a) Open Visual Studio 2010 and select File à New à Web Site. In the New Web Site dialog, select the ASP.Net Web Site template and enter the location to store the web site files. Please see the image below:

You can choose any location whichever is comfortable for you. web.config file will be added to project automatically.

b) By default, you will see a <connectionStrings/> node within <configuration> node. Specify the connection string to the database which has been created in the previous section. Please see the image below:

I have mentioned server as GUNAGA1. This is the server in which SQL Server 2008 is installed. Please mention the respective server name.

Also add the membership provider and role provider within <system.web> tag. See the below image for more information.

c) Save web.config file and launch the ASP.Net Configuration Wizard by clicking on Website à ASP.Net Configuration. Please see the image below:

d) Set the authentication type in the above wizard. To do this, click Security link. In the Security tab, under Users section, click Select authentication type link. Select From the internet option and press Done button which is available in the bottom right corner. By selecting this option, which means that site will use form authentication to identify users. Please see the image below:

e) To test the membership and role providers, click on Provider tab. In the Provider tab, click on Select a different provider for each feature (advanced) link. Select right / correct membership and role provider and click Test link to ensure that providers are communicating to right database.

At this point, we configured web.config file with connection string and providers information. Also we tested the providers with the database. Next section will explain adding users to database.

Create a User

a) To add users, click on Security tab. In Security tab, under Users section, click Create user link. Here I am adding user as testFBA and password as password which will be used for testing form authentication later. Please see the image below:

Now we have created a user successfully. Do not worry about creating roles at this time and will be explained later.
