**Versions**  
opensearch-2.4.1

**Describe the issue** :  
any Securityadmin.sh commands fail , as opensearch.yml contains: /plugins.security.ssl.http.clientauth\_mode: NONE

connect as “null”

It seem’s that solution consist in removing :  
/plugins.security.ssl.http.clientauth\_mode: NONE from opensearch.yml

as transport client auth\_mode has been removed in opensearch 2 version

when I delete this line : securityadmin.sh commands succeed (with opensearch-2.4.1)

Can you confirm that the line “/plugins.security.ssl.http.clientauth\_mode: NONE” :

- must be removed from opensearch.yml for opensearch version greater than 2.0.0
- must be kept in opensearch.yml for opensearch version lower than 2.0.0
