How to Remove the Windows Authentication Option from the ExCM default Sign In Page

Some organizations require that their external facing sign-in page only be designed to allow FBA or Forms Based Authentication users to log in to a site collection. This requirement can be met by removing the default "Window Authentication" sign-in option from the sign-in page. Below are the instructions for making this change to the PremierPoint Solutions default ExCM sign-in page.

Here is an example of the default sign-In page with the Windows Authentication option.

To remove the Windows Authentication option you will first need to browse out to C:Program FilesCommon FilesMicrosoft SharedWeb Server Extensions15TEMPLATELAYOUTSSPSolutionsExCM

Next, you will need to make a copy of the existing SignIn.aspx page and save it, so that you maintain an original.

Now, open the "SignIn.aspx" page and do a search for "RepeaterAuthenticationProviders".

Once you finish the search you will then need to remove the <%$Resources:excm,Page_SignIn_SignInUsing%> from quotations in the fifth SharePoint line and then completely delete the sixth line <%# DataBinder.Eval(Container.DataItem, "ClaimProviderName") %></a>

<asp:Repeater ID="RepeaterAuthenticationProviders" DataSourceID="ExtranetAuthenticationProvidersDS" runat="server">
<ItemTemplate>
<div class="excm_signin_action">
<a href="javascript:AuthenticationProviderSignIn('<%# DataBinder.Eval(Container.DataItem, "ClaimProviderName") %>')">
<SharePoint:EncodedLiteral runat="server" EncodeMethod="htmlEncode" Text="<%$Resources:excm,Page_SignIn_SignInUsing%>" />
<%# DataBinder.Eval(Container.DataItem, "ClaimProviderName") %></a>
</div>
