Hello Yang,
I try authenticate with the curl:
curl -u kibanaadmin:*** http://localhost:9200/_security/_authenticate
and the output was:
{"error":{"root_cause":[{"type":"security_exception","reason":"unable to authenticate user [kibanaadmin] for REST request [/_security/_authenticate]","header":{"WWW-Authenticate":"Basic realm=\"security\" charset=\"UTF-8\""}}],"type":"security_exception","reason":"unable to authenticate user [kibanaadmin] for REST request [/_security/_authenticate]","header":{"WWW-Authenticate":"Basic realm=\"security\" charset=\"UTF-8\""}},"status":401}
And I can't authenticate...
Thank you for your help.
