Could not authenticate the user about kafka-connect-opensearch HOT 5 CLOSED

As a side note, using connection.username and connection.password is also what we do (successfully) in the integration tests.

Yes resolved, this issues was due to the plugins.security.ssl.http=true in the OpenSearch configuration. Setting that option to false allowed http request without SSL verification. This issue was not from this library.
Thanks

I'm using the plugin with a database provided by Aiven and a similar config without any problem. Could this be coming from your database?

Note that I'm maintaining this plugin out of necessity. But without any recent java experience. So I'd definitely recommend you not to rely too much on any guidance through GitHub issues, and to do your own investigations instead (PRs are welcome if you find any issue).

Thanks for confirming @dmathieu .
I'm using the plugin with self-managed OpenSearch. So, I'll look into this if I need to do anything with OpenSearch to solve this issue. By the way I was just confirming that if I was making any mistake in plugin config or not. Moreover, I also found similar kind of issue in https://discuss.opendistrocommunity.dev/t/opendistro-kafka-connect/ here (not exactly same) so I also tried that and then after I created this issue to check if plugin has any issues regarding authentication.

Have you been able to resolve this issue on your end?
I'm going to close the issue, as it appears to be a local OpenSearch issue rather than one with the library.
