FBA in sharepoint provider hosted app in sharepoint 2013

Hi All,

I am trying to create a provider hosted app in sharepoint with FBA Authentication. I already have a basic provider hosted app and I wanted to add FBA authentication to it. I changed the web config file as below after adding a login page

   <authentication mode="Forms">
      <forms loginUrl="Pages/Login.aspx">

      </forms>
    </authentication>
    <authorization>
      <deny users="?"/>
    </authorization>
    <membership defaultProvider="fbaMember">
      <providers>
        <add connectionStringName="fbaSQL" applicationName="/" name="fbaMember" type="System.Web.Security.SqlMembershipProvider, System.Web,&#xA;      Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
      </providers>
    </membership>
    <roleManager enabled="true" cacheRolesInCookie="false" defaultProvider="fbaRole">
      <providers>
        <add connectionStringName="fbaSQL" applicationName="/" name="fbaRole" type="System.Web.Security.SqlRoleProvider, System.Web,&#xA;      Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
      </providers>
    </roleManager>

 <connectionStrings>
 
    <add name="fbaSQL" connectionString="server=servername;database=dbNameOfMemberShip;Trusted_Connection=true"/>

  </connectionStrings>

 <add key="ClientID" value="111-111--111-****" />
    <add key="ClientSecret" value="222-*******" />
      <add key="ClientSigningCertificatePath" value="C:\Path\CertName.pfx" />
      <add key="ClientSigningCertificatePassword" value="password" />
      <add key="IssuerId" value="23232*******" />


    <add key="MembershipProviderName" value="FbaMember"/>

Then I disabled the Windows authentication in the IIS of asp.net application. But after that, when I access the Client web parts and asp.net application, I am getting the following error:

"401 - Unauthorized: Access is denied due to invalid credentials".

Can somebody provide me the information on creating a Provider hosted app with FBA authentication.

Any help will be appreciated

Regards

Vishnu
