> According to LDAP specification [1]: "Clients that follow referrals MUST ensure that they do not loop between servers. They MUST NOT repeatedly contact the same server for the same request with the same parameters.".
> When application server is configured to use ldap-realm with dir-context which uses referral-mode=follow or throw and LDAP servers contain loop then it leads to infinite cycle. It can results to java.lang.OutOfMemoryError on EAP server.
