MVC Forms LoginUrl is incorrect 7 answers

I am at a total loss here. This was working earlier. I have an MVC3 app using forms authentication. In web config, I have the following:

<authentication mode="Forms">
  <forms loginUrl="~/Login/Index" timeout="2880"/>
</authentication>

Yet, for some reason, when redirecting, or when checking FormsAuthentication.LoginUrl, its still using the default /Account/Login. Which doesn't exists. Why isnt the web.config overriding this?

回答1:

Try adding this to appSettings in your web.config:

<add key="loginUrl" value="~/Account/LogOn" />

I have also had these issues and it only happened when i had added deployable assemblies and webmatrix.dll was added. That is when it started to try to redirect to an Account Controller which was not specified anywhere in my project.

Once i removed webmatrix.dll everything worked as intended.
