Hi Team,

I am new to this zookeeper.
I was trying to understand the SASL concept in zk.
I have tried to run "SaslAuthDesignatedClientTest".
But got the testcase failed. Do I need to modify anything?
Am I learning in the correct way?
Why this AuthFailed happens? How to overcome this?

Hi,

I am trying to implement Digest MD5 SASL authentication.
While I have given the correct username and password its getting connected to zk and working fine as expected.

But if I give wrong password I am expecting "AuthFailed" exception message.
But I am getting the keeper state as "Disconnected" and the "ConnectionLoss" exception is thrown.

What I am doing wrong?

While checking in the zk server console getting the following log
