             Summary: Usernames started with rdn-identifier works incorrectly in Elytron ldap-realm
                 Key: WFLY-7302
                 URL: https://issues.jboss.org/browse/WFLY-7302
             Project: WildFly
          Issue Type: Bug
          Components: Security
            Reporter: Ondrej Lukas
            Assignee: Darran Lofthouse
            Priority: Critical


In case username passed to {{org.wildfly.security.auth.realm.ldap.LdapSecurityRealm$LdapRealmIdentity}} starts with the same string as is used in {{identityMapping.rdnIdentifier}} then authentication fails. It is caused by wrong condition in [1].

Thrown exception in server log:
