[Quick Fix] An operations error occurred at System.DirectoryServices.AccountManagement.ADStoreCtx.FindPrincipalByIdentRefHelper

As a reference to people running code that is talking to Active Directory and are getting this cryptical message. In most cases it is a permissions issue. Make sure that your code is running under the application pool account (meaning SPSecurity.RunWithElevatedPrivileges) and that this account has the necessary rights to do so on AD.
