             Summary: fips-mode parameter in the configuration doesn't work as expected
                 Key: ZOOKEEPER-4973
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4973
             Project: ZooKeeper
          Issue Type: Task
          Components: java client, security, server
    Affects Versions: 3.9.4
            Reporter: Jota Martos


When using Zookeeper 3.9.4, I was trying to disable FIPS by setting the "fips-mode" parameter to false in the configuration as described in [the documentation|https://zookeeper.apache.org/doc/r3.9.4/zookeeperAdmin.html]. 

{code}
$ cat /path/to/zoo.cfg
...
fips-mode=false
...
{code}

However, that doesn't disable FIPS and I get errors when trying to configure authentication
