Elytron/Remoting/EJB - Exception from failed authentication differs depending on previous calls ----------------------------------------------------------------------------------------------- Key: ELY-1423 URL: https://issues.jboss.org/browse/ELY-1423 Project: WildFly Elytron Issue Type: Bug Components: Authentication Client Affects Versions: 1.2.0.Beta8 Reporter: Jan Kalina Assignee: Jan Kalina Priority: Critical Exception presented to a client when EJB authentication fails should be the same for first authentication and subsequent authentications. I have following scenario: {noformat} EJB Client -> EntryBean (server1) -> WhoAmIBean (server2) {noformat} the Client provides correct credentials to server 1 and EntryBean makes reauthentication to server2. When I use  wrong credentials for server2 in EntryBean, the call fails with: {noformat} org.jboss.ejb.client.RequestSendFailedException: javax.security.sasl.SaslException: Authentication failed: all available authentication mechanisms failed {noformat} When I run the scenario twice and use a correct credentials in EntryBean first and wrong in the second run, then the Exception is different: {noformat} org.jboss.ejb.client.RequestSendFailedException: org.wildfly.security.auth.AuthenticationException: JBREM000308: Authentication failed (no mechanisms left) {noformat} From a client POV the exception should be the same in every call: * to allow safer exception handling in client code * to avoid disclosure shared connection details
