Marc Richter commented on ZOOKEEPER-2365:
-----------------------------------------

Sorry to be the necromancer here, commenting a ~3 year old report, but obviously, noone ever picked up work on this and it seems to be the same issue with recent versions.

> I have zookeeper running normally just fine in a 3-server cluster.
> Then I try to configure zookeeper to use Kerberos, following docs in the Solr wiki here: https://cwiki.apache.org/confluence/display/solr/Kerberos+Authentication+Plugin
> I can't even get to the fun Kerberos errors. When I start with {{JVMFLAGS="-Djava.security.auth.login.config=/opt/zookeeper/jaas-server.conf"}}
> and this jaas-server.conf:
> {code}
> Server {
> com.sun.security.auth.module.Krb5LoginModule required
> useKeyTab=true
> keyTab=/keytabs/vdev-solr-01.keytab
> storeKey=true
> doNotPrompt=true
> useTicketCache=false
> debug=true
> principal="HTTP/<snip>";
> }
> {code}
> I get this in the log:
> {code}
> 2016-02-10 16:16:51,327 [myid:1] - ERROR [main:ServerCnxnFactory@195] - No JAAS configuration section named 'Server' was foundin '/opt/zookeeper/jaas-server.conf'.

> I get the exact same error if the jaas-server.conf file exists, or does not.
> So later I found that the Solr wiki was wrong and lost the double quotes around the keytab value. It would be nice if Zookeeper spewed a more useful message when it can't parse the configuration.
