Yes, user can enable SASL for Observer nodes as well. In general, QuorumLearner will send authentication packet to peer QuorumServer. Observer is a learner which follows the same quorum authentication protocol and auth logic will work fine. FYI, hope you are referring below links for configurations, https://cwiki.apache.org/confluence/display/ZOOKEEPER/Server-Server+mutual+authentication https://blog.cloudera.com/blog/2017/01/hardening-apache-zookeeper-security-sasl-quorum-peer-mutual-authentication-and-authorization/ Please let us know if you are facing any issues.
