{
if(dataAccess == null)
throw new ArgumentNullException("dataAccess");
if(string.IsNullOrWhiteSpace(identity))
throw new ArgumentNullException("identity");
var conditions = MembershipHelper.GetUserIdentityConditions(identity, @namespace);
var record = dataAccess.Select<IDictionary<string, object>>(MembershipHelper.DATA_ENTITY_USER, conditions, "!, UserId").FirstOrDefault();
var result = record != null && record.Count > 0 && record.ContainsKey("UserId");

if(dataAccess == null)
throw new ArgumentNullException("dataAccess");
if(condition == null)
throw new ArgumentNullException("condition");
password = null;
