----------------------------------

             Summary: Provide X509ZkAclProvider for X509 Zookeeper 
Authentication and ACLs
                 Key: SOLR-13673
                 URL: https://issues.apache.org/jira/browse/SOLR-13673
             Project: Solr
          Issue Type: Wish
      Security Level: Public (Default Security Level. Issues are Public)
          Components: SolrCloud
    Affects Versions: 8.2, master (9.0)
            Reporter: Jörn Franke


ZooKeeper supports X509 authentication and ACLs towards Zookeeper servers. It 
seems that when enabling SSL support in ZooKeeper 3.5.5 and ACLs only X509 ACLs 
are allowed and others (e.g. Kerberos Authentication and ACLs with SSL enabled) 
are not possible (see also: 
https://issues.apache.org/jira/browse/ZOOKEEPER-3482).

Furthermore, in highly automised cloud environments and enteprise environments, 
X509 authentication and ACLs could be an attractive alternative compared to 
Kerberos.

Solr should thus support a X509ZkAclProivder for X509 Zookeeper Authentication 
and ACLs.
