@san_re The configuration of Remote Url in InvokeHTTP should be as follows:

/j_security_check?j_username=${j_username}&j_password=${j_password}

Notice the credential values are passed to the url with the ?.  This is the only change in the processor config.

Here is a demo flow:

GenerateFlowFile - starts flow for testing

UpdateAttribute - sets user, pass,and mime type attributes needed in InvokeHttp

InvokeHttp - sends POST

You can find this template on my GitHub to inspect the entire flow:
