Security :: Admin And User Security Folder Setup

I am creating an application hosted on GoDaddy.com. The base files are kept in a folder called /sky while the Admin files and User files are kept in /sky/Admin and /sky/User respectively. I'm having difficulty configuring the security so that when a user tries to access Admin or User files they should be redirected to the login.aspx file in the /sky folder. I keep getting an error that its trying to access sky/sky/login.aspx instead of just sky/login.aspx.

Here are the relevant sections of my web.config file.

<?xml version="1.0"?>
<configuration>
...
<location path="sky/admin">
<system.web>
<authorization>
<allow roles="Admin" />
<deny users="*"/>
</authorization>
</system.web>
</location>
<location path="user">
<system.web>
<authorization>
<allow roles="Admin,User" />
<deny users="*"/>
</authorization>
</system.web>
</location>
<system.web>
<customErrors mode="Off" />
<authentication mode="Forms">
<forms name="login" loginUrl="login.aspx" />
</authentication>
...
</system.web>
...
</configuration>

Can someone point me to articles or provide assistance with the proper configuration?
