I am trying to retrospectively plug in Forms Authentication to an ASP.Net project that was originally created with the no authentication template using VS 2013 and ASP.Net 4.0
I have followed the advice on MSDN and added this to my Web Config under system.web
<authentication mode="Forms"><forms loginUrl="Logon.aspx" name=".ASPXFORMSAUTH"></forms></authentication><authorization><deny users="?" /></authorization>
When I launch the site (IIS 7) the URL redirects to the Logon.aspx page but then I get a Error message 401.2.: Unauthorized: Logon failed due to server configuration.
In IIS I have the website set for Anonymous and Forms based authentication enabled.
Am I missing something here?
Edit: The issue is the same as reported here: https://social.msdn.microsoft.com/Forums/sqlserver/en-US/2920a4e2-775a-4aa7-bfff-4931fa0a4e9a/azure-website-forms-authentication-issue?forum=windowsazurewebsitespreview
It looks like there is an issue with Forms authentication being applied to ASP.Net projects from the VS templates.
