Membership Role Provider doesn't work with custom connection string? - asp.net

Question

plz help with one issue.
I have Membership configured with IIS7, tables for it located in my own database, created with aspnet_regsql utility, and I am using custom connection string to access it.
This is part of web.config related to Membership :
<connectionStrings>
<add connectionString="Server=CORESERVER\SQLExpress;Database=Shop;User ID=Tema;Password=Matrix" name="CustomSqlConnection" />
</connectionStrings>
<profile enabled="true">
<providers>
<add name="CustomSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="CustomSqlConnection" />
</providers>
</profile>
<roleManager defaultProvider="AspNetSqlRoleProvider" enabled="true">
<providers>
<add name="CustomSqlRoleProvider" type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="CustomSqlConnection" />
</providers>
</roleManager>
<membership defaultProvider="CustomSqlMemberProvider">
<providers>
<add name="CustomSqlMemberProvider" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="CustomSqlConnection" enablePasswordReset="true" enablePasswordRetrieval="false" passwordFormat="Hashed" requiresQuestionAndAnswer="true" requiresUniqueEmail="true" applicationName="/" maxInvalidPasswordAttempts="10" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" passwordStrengthRegularExpression="" />
</providers>
</membership>
<authentication mode="Forms">
<forms cookieless="UseCookies" loginUrl="login.aspx" name="WebShopAuthentication" protection="All" timeout="30" path="/" requireSSL="false" defaultUrl="~/admin/default.aspx" />
</authentication>
<authorization>
<allow users="*" />
</authorization>
And ... Forms authorization, getting user and his membership info is OK.
But ... getting roles is always FALSE.
MembershipUser userData = Membership.GetUser(HttpContext.Current.User.Identity.Name); // OK !!! IT IS GREAT :)
var a = new RolePrincipal(HttpContext.Current.User.Identity);
var aa = a.getRoles(); // {string[0]} - EMPTY!!!
var b = Roles.IsUserInRole("Administrator", "Administrator"); // FALSE!!!
var c = Roles.Providers["CustomSqlRoleProvider"].GetAllRoles(); // {string[0]} - EMPTY!!!
var d = Roles.IsUserInRole(HttpContext.Current.User.Identity.Name, "Administrator"); // FALSE!!!
var e = HttpContext.Current.User.IsInRole("Administrator"); // FALSE !!!
WHYYYY???
What am i doing wrong???

Answer 1

Just to refine ... authorization works fine and uses roles correctly. Another part of my web.config :
<location path="Admin">
<system.web>
<pages styleSheetTheme="Admin" theme="Admin">
</pages>
<authorization>
<deny users="?" />
<allow roles="Administrator" />
</authorization>
</system.web>
<appSettings>
<add key="ThemeName" value="Admin" />
</appSettings>
</location>
And then in code is used :
Membership.ValidateUser(userName.Text, userPassword.Text) // AND IT WORKS - USER IS LOGGED IN

Answer 2

The answer is that i didn't add applicationName parameter to web.config correctly - after adding i should restart IIS and if needed recreate roles.
This is final version of web.config :
<roleManager defaultProvider="CustomSqlRoleProvider" enabled="true">
<providers>
<add name="CustomSqlRoleProvider" type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="CustomSqlConnection" applicationName="/" />
</providers>
</roleManager>
