Observer properties for SASL authentication in 3.4.13 version

[rammohan ganapavarapu]

Hi,

Do we need to configure any thing on observer nodes for SASL
authentication?

tcpKeepAlive=true ( this is not for sasl but just asking )

quorum.auth.enableSasl=true
quorum.auth.learnerRequireSasl=true
quorum.auth.serverRequireSasl=true

What will happen if i set these properties on observers nodes as well ?

Thanks,
Ram
