   internal static IEnumerable<string> GetSecurityGroups()
    {
        try
        {
            ClaimsPrincipal claimsPrincipal = null;
            claimsPrincipal = Thread.CurrentPrincipal as ClaimsPrincipal;
            claimsPrincipal = ((claimsPrincipal == null) && (HttpContext.Current.User != null))
                ? HttpContext.Current.User as ClaimsPrincipal
                : claimsPrincipal;
            if (claimsPrincipal != null)
            {
                return ((ClaimsIdentity)claimsPrincipal.Identity).Claims
                    .Where(
                        claim =>
                            "group".Equals(claim.Type.Replace("http://sts.tmft.net/user/", ""),
                                StringComparison.InvariantCultureIgnoreCase))
                    .Select(c => c.Value).ToList();
            }
        }
        catch (Exception exception)
        {
            Log.Error(exception);
        }
        return new[] { "No rights" };
    }
