Hello everyone. I upgraded my test environment cluster from 8.11.1 to 9.0.0 and
I'm experimenting this issue. Anytime I start the solr service I get this error

... 55 more{code}
When I rollback to 8.11.1 with exactly the same configuration I don't
experiment this issue.
I tried:
1. Set the "SOLR_JETTY_HOST="0.0.0.0"
2. Set the "SOLR_MODULES=hadoop-auth" because it uses kerberos too.
3. I read the documentation about
[Kerberos|https://solr.apache.org/guide/solr/latest/deployment-guide/kerberos-authentication-plugin.html]
Authentication and it's pretty similar to the 8.11.1 version.
4. I modified my security.json like this:
{code:java}
{"authentication": {"class": "solr.KerberosPlugin"}}{code}
I don't know if there's something missing on the documentation or if I doing
something wrong, which is the most probably.
I hope the issue is well described, I searched in the web but I haven't found
anything related.
Best regards.
