I am invoking an API command (nifi-api/access/token) to get the access token. But i am getting error like this java.net.SSLHandShakeException unable to find valid certification path for requested target. we have LDAP configured in NiFi Cluster and i am able to login to NiFi UI using my credentials. I have started exploring the NiFi rest API for the first time. Any help would be appreciated !!
(P.S I want to use rest api by codes and native processors ( i can do in simple nifi which i have on my desktop) how can i make my task on nifi with kerberso autentification?
Thank you in Advance.
import certificate into truststore.jks using keytool. then in the invokehttp processor use SSL Context Service that should point to your truststore.jks

NIFI is unable to connect to URL with https using invokeHTTP Processor, no certificate is required to access the site via browser(only user & pass).
The error observed is "Request Processing Failed: javax.net.SSLPeerUnverifiedException".
I have tried adding SSL Context with Java Truststore and nifi Keystore. But it is not working.Kindly suggest.
When using InvokeHTTP to connect to a HTTPS URL, you will need to add an SSLContextService which InvokeHTTP can use to verify the remote server. The SSLContextService will refer to a truststore which contains the public Certificate Authority. For example if connecting to stackoverflow with NiFi, you would need the CN = ISRG Root X1, O = Internet Security Research Group, C = US installed in a pkcs12 truststore, which is used by the SSLContextService. Another option is to use the truststore provided by Java, typically located at $JAVA_HOME/lib/security/cacerts, which will trust most publicly signed web domain certificates.
Please add more details of the error message if this still is not working.
So I am trying to make GET request and as Remote URL I am using this open api endpoint.
But InvokeHTTP processor shows an error: Unable to find valid certification path to requested target
So since I am new to nifi I didn't touch any other setting.
Can someone please help me with proper configuration for this?
Thank you beforehand!
Set a SSL Context Service property (https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-ssl-context-service-nar/1.6.0/org.apache.nifi.ssl.StandardSSLContextService/index.html) in the InvokeHTTP processor
According to the documentation, one prerequisite for using NiFi CLI against a secured NiFi instance is to configure proxy user request for the node's identity (e.g. CN=localhost, OU=NIFI).
https://nifi.apache.org/docs/nifi-docs/html/toolkit-guide.html#prerequisites-for-running-in-a-secure-environment
I understand how to configure it through the NiFi web user interface. However, is it possible to do the same through scripting?
The reason is that I am working on a NiFi installation script, and I would like to install NiFi and configure users/policies in one go if it is possible.
Thank you!
If you are trying to use NiFi CLI to setup NiFi itself, then you're only real option is for NiFi CLI to perform operations as the Initial Admin identity.
It then depends how NiFi is configured to perform authentication, meaning where is your initial admin identity coming from. Is it a DN from a client cert, a user in LDAP, a kerberos principal, etc?
If it is a client cert, then you can just configure NiFi CLI to use that cert and it should work.
If it is a LDAP user, then you need to have NiFi CLI use one of NiFi's server certs to proxy the LDAP user.
Both of these scenarios are shown in the docs:

I am new to OpenID connect & security domain. I have configured Nifi to use OpenID for authentication using online documentation. And to automate a few nifi related tasks we are using nipyapi.
I have already written python code which does automated flow deployment for basic nifi installation (unsecured & without user authentication)
Now, I have to move the code to secured Nifi installation. How to authenticate to OpenID connect using nipyapi/rest API ?
AS per discussion with Bryan, i am planning to use client certificate for authentication but it started giving authorization error. and have created another question with the details.
Nifi - Client Certificate Authorization Error
OpenID Connect generally requires that you follow a flow of re-directs, typically in the browser. NiFi re-directs you to the login page of the OIDC provider, upon completion, the OIDC provider redirects you back to NiFi. I'm not exactly sure how, or if you even can, perform this login process from scripts. An easy alternative would be to just generate a client certificate to represent an automation user for any NiPyApi scripts. Client certificate authentication is always enabled by default for NiFi.
I'm trying to connect to s4 hana system using s4 sdk. While executing calls via .execute() method in cloud foundry environment, i see below error logs:
Caused by: com.sap.cloud.sdk.cloudplatform.connectivity.exception.DestinationAccessException: Failed to get authentication headers. Destination service returned error: Missing private and public key for subaccount ******-****-****-***-*******.
Note: I've already configured trust between subaccount and S4Hana system and created respective communication and business user. The associated authentication method used in the destination is oAuth2SamlBearerAssertion. Note: The call executes fine in both local and cloud foundry environment with basic authentication.
Can someone please suggest what is wrong here.
As correctly pointed out by #Dennis H there was a problem in trust configuration between my subaccount and S4 Hana system, the configuration wrong in my case :
-> The certificate I downloaded for trust was using this URL:
https://.authentication.eu10.hana.ondemand.com/saml/metadata
This is incorrect we need to get the certificate from download trust button in destination tab at subaccount level
->Provider name was incorrect in the communication system.
We are developing a side-by-side extension app and deploying it to CF. Our app is trying to connect to S4HANA cloud system using oAUTH2SAMLBEARERASSERTION. But facing issues while doing it. We are getting below error in logs. Please be noted, we are able to connect to S4HANA Cloud using basic auth.
com.sap.cloud.sdk.cloudplatform.connectivity.exception.DestinationAccessException: Failed to access the configuration of destination
Our destination parameters look as attached screenshotenter image description here
Thank you.
