Hi,

I installed the following modules:  
elasticsearch-6.3.1  
kibana-6.3.1-windows-x86\_64

search-guard-6-6.3.1-22.3

search-guard-tlstool-1.5

jdk1.8.0\_181

jre1.8.0\_181

The elastic search and the kibana are working. And first I can run sgadmin, so I could create the certificates. After that I want to add new users to internal\_users. But the sgadmin (use the same command) cause the next error:

Error: A JNI error has occurred, please check your installation and try again

Could you help me? I can’t find the problem ☹

Sorry, I don’t fully understand this issue. First, how exactly did you install Search Guard? And what does your elasticsearch.yml look like?

When you say:

“And first I can run sgadmin, so I could create the certificates”

what do you mean? Did you run sgadmin successfully? And how does running sgadmin relate to creating certificates?

“But the sgadmin (use the same command) cause the next error”

I also don’t understand, sorry. Do you mean you ran sgadmin once successfully, and the exact same command failed the second time?

What exact command did you run?

Sorry, it’s my fault. I’m beginner and it’s my first installation. That step was the created the certificates for me. But it contain create the certificates with Offline TLS Tools and after that pushed configuration changes to SG with sgadmin.  
The command was:  
sgadmin.bat -cd ..\sgconfig\ -icl -nhnv -cacert ......\config\root-ca.pem -cert ......\config\kirk.pem --hostname desktop-v10o5he -key ......\config\kirk.key -keypass 7zojtw0eJTIF  
It worked. Next step was configuring the elastic.yml and kibana.yml. The ES and the kibana works and run in https. When I tried add new users to Kibana I modified the sg\_internal\_users. If I know well I have to run sgadmin again (I use the same command first, after I try this: ./sgadmin.sh -f ../sg\_internal\_users.yml -t internalusers -ts … -tspass … -ks … -kspass … with the correct values) But I got the upper exception. And I don’t know why.

My full elastic.yml:
