> I'm trying to set up a cluster of 3 Zookeeper nodes and I'm struggling to
> understand the error messages regarding jaas.conf file.
> I found 2 articles about the [Server-Server mutual
> authentication|[https://cwiki.apache.org/confluence/display/ZOOKEEPER/Server-Server+mutual+authentication]]
> jaas.conf file are the same on 3 nodes and it seems to be working:
> |{{QuorumServer {}}
> {{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
> {{ user_zkinternal="pa$$word";}}
> {{};}}
> {{ }}
> {{QuorumLearner {}}
> {{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
> {{ username="zkinternal"}}
> {{ password="pa$$word";}}
> {{};}}|
> Now I want to connect a Solr client to it. I found an article about
> [Client-Server mutual
> authentication|[https://cwiki.apache.org/confluence/display/ZOOKEEPER/Client-Server+mutual+authentication]]
> It show an example:
> |{{Server {}}
> {{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
> {{ }}{{user_super=}}{{"adminsecret"}}
> {{ }}{{user_bob=}}{{"bobsecret"}}{{;}}
> {{};}}|
> The problem when I try to change my original jaas.conf file with something
> else like:
> |{{QuorumServer {}}
> {{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
> {{ user_zkinternal="pa$$word";}}
> {{ user_solr=}}{{"solrsecret"}}{{;}}{{}}
> {{};}}
> {{ }}
> {{QuorumLearner {}}
> {{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
> {{ username="zkinternal"}}
> {{ password="pa$$word";}}
> {{};}}|
> or
> |{{QuorumServer {}}
> {{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
> {{ user_zkinternal="pa$$word";}}{{}}
> {{};}}
> {{ }}
> {{QuorumLearner {}}
> {{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
> {{ username="zkinternal"}}
> {{ password="pa$$word";}}
> {{};}}
> {{}}
> {{}}
> {{Server {}}
> {{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
> {{user_solr=}}{{"solrsecret"}}{{;}}{{}}
> {{};}}|
> or even
> |{{QuorumServer {}}
> {{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
> {{ user_zkinternal="pa$$word"}}{{}}{{}}
> {{};}}
> {{ }}
