Other - Catastropic Error

I'm using Windows Authentication and trying to test if the user is in a group. The code is as follows:


Code SnippetSystem.Web.Security.WindowsTokenRoleProvide r.GetRolesForUser(String username)








web.config to enable Role Manager


Code Snippet<authentication mode="Windows"/>

<roleManager defaultProvider="WindowsProvider" enabled="true" cacheRolesInCookie="false">

<providers>

<add name="WindowsProvider" type="System.Web.Security.WindowsTokenRoleProvider" />

</< FONT>providers>

</< FONT>roleManager>







An exception ocuurs on :


Code SnippetSystem.Web.Security.WindowsTokenRoleProvide r.GetRolesForUser(String username)







API failed due to error 'Catastrophic failure'


Anyone has any idea of what is wrong:

Thanks.
