SASL for Client connections

[Harish kumar]

Hi,

I have enabled SASL on my Zookeeper, with below configuration.

*requireClientAuthScheme=sasl*
*authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider*

But still I see that, I am able to connect to zookeeper even without a
valid kerberos ticket.
Is there a way to restrict all client connections only with valid kerberos
ticket.

Zookeeper Version - 3.4.8


Thanks,
Harish
