  • Use the default setting, never, for all external authentication mechanisms to prevent referral chasing, unless you have a good reason to follow referrals.
  • If LdapClientReferrals is set to yes, use the LdapClientDeref property to tell the directory how to handle the referrals it finds. Also see LdapClientReferrals.
