[jboss-jira] [JBoss JIRA] (WFLY-7946) Elytron ldap-realm does not handle loops in referrals

Elytron ldap-realm does not handle loops in referrals ----------------------------------------------------- Key: WFLY-7946 URL: https://issues.jboss.org/browse/WFLY-7946 Project: WildFly Issue Type: Bug Components: Security Affects Versions: 11.0.0.Alpha1 Reporter: Ondrej Lukas Assignee: Darran Lofthouse Priority: Critical Attachments: print-roles.war 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. This issue has been already reported for legacy security during EAP 7.0.0 testing in JBEAP-2156.
