> There are a host of errors that can happen when logging into an LDAP-enabled Hive-server2
from beeline.  But for any error there is only a generic log message:
> {code}
> SASL negotiation failure
> javax.security.sasl.SaslException: PLAIN auth failed: Error validating LDAP user
> 	at org.apache.hadoop.security.SaslPlainServer.evaluateResponse(SaslPlainServer.java:108)
> 	at org.apache.thrift.transport.TSaslTransport$SaslParticipant.evaluateChallengeOrRespons
> {code}
> And on Beeline side there is only an even more unhelpful message:
> {code}
> Error: Invalid URL: jdbc:hive2://localhost:10000/default (state=08S01,code=0)
> {code}
> It would be good to print out the underlying error message at least in the log, if not
beeline.   But today they are swallowed.  This is bad because the underlying message is the
most important, having the error codes as shown here : [LDAP error code|https://wiki.servicenow.com/index.php?title=LDAP_Error_Codes]
> The beeline seems to throw that exception for any error during connection, authetication
or otherwise.
