יש לי בעיה ב SECURITY ב ROLES וכל הזמן מופיע לי את הבעיה הזאת כשאני לוחצת על Create or Manage roles

The following message may help in diagnosing the problem: The configured Role Provider (WindowsTokenRoleProvider) relies upon Windows authentication to determine the groups that the user is allowed to be a member of. ASP.NET Role Manager cannot be used to manage Windows users and groups. Please use the SQLRoleProvider if you would like to support custom user/role assignment. at System.Web.Administration.WebAdminPage.CallWebAdmi nHelperMethod(Boolean isMembership, String methodName, Object[] parameters, Type[] paramTypes) at ASP.security_roles_manageallroles_aspx.BindGrid() at ASP.security_roles_manageallroles_aspx.Page_Load() at System.Web.Util.CalliHelper.ArglessFunctionCaller( IntPtr fp, Object o) at System.Web.Util.CalliEventHandlerDelegateProxy.Cal lback(Object sender, EventArgs e) at System.Web.UI.Control.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
