Missing username in LDAP entry for legacy ldap realm returns 500 instead of 401 ------------------------------------------------------------------------------- Key: WFCORE-2257 URL: https://issues.jboss.org/browse/WFCORE-2257 Project: WildFly Core Issue Type: Bug Components: Security Reporter: Ondrej Lukas Assignee: Darran Lofthouse Fix For: 3.0.0.Beta3 In case when legacy LDAP Realm uses {{username-load}} attribute and its value does not exist in LDAP entry then current implementation returns status code 500. This is different behaviour from WildFly 10 where status code 401 is returned. This issue can be related to WFCORE-2258 (500 return for nonexistent user in legacy ldap security realm).
