Nevermind I figured it out. I realized I forgot to add something in my Dockerfile to import the ca certificate into java cacerts.

Hello, I am working on getting registry setup using docker and for some reason I can't seem to get LDAP authentication to work. This is a snippet of the error I am getting when I try to login: 2025-07-17 19:24:09,286 DEBUG [NiFi Registry Web Server-28] o.s.s.l.authentication.BindAuthenticator Failed to bind with any user DNs []

I have my a Dockerfile setup copy the certificates to the container and run update-ca-certificates. I'm not really sure what the issue is at this point. I used a similar setup for my nifi container and it works as it should, but for some reason registry doesn't like credentials when I try to login. Any helps is appreciated!

@MattWho Is there anywhere I can find what types of filters I can use in the "User Search Filter" or the Group one? I am trying to widdle down the amount of objects that are populated from LDAP into my Users. In my AD Server, users are in 2 different OU's. So, for example, I'll have users in ou=Admin Accounts,ou=Domain Admins,dc=my,dc=network,dc=com but I'll also have users in ou=Regular Users,ou=Testers,dc=my,dc=network,dc=com. And the only way to really pull both are to have my base search set to dc=my,dc=network,dc=com. Doing this pulls computer accounts and all users, even users that would never need access (like service type accounts). I can filter out the computer accounts by using this filter: (objectCategory=cn=Person,cn=Schema,cn=Configuration,dc=my,dc=network,dc=com) But I'd like to also filter out the accounts, or OU's that aren't needed. Or, if possible just use the 2 NiFi groups I have in AD (Nifi Admins/Nifi Users) without having to populate all of my AD users, if that makes sense.

Hello, I have setup NiFI 2.1.0, and am trying to figure out how to allow users in a NiFi Microsoft AD Group to authenticate to the GUI. I have it setup so users can log in if I add their LDAP account. But, I'd rather just have users in the group I created in AD be able to login instead of having to go in and add new users to NiFi each time. Here are the configs I have setup for my authorizers.xml: <userGroupProvider>

</provider> After I configure these I am not really sure what else I would need to do as the documentation doesn't provide much instruction on what to expect after configuring these. Are the AD groups supposed to be automatically added to NiFi? Or do I need to add the group to NiFi manually? I tried manually adding to just to see but the account I was using to test still couldn't login. Thanks in advance for helping!

@MattWho I was able to get this resolved. It didn't require adding any other certificates other than my CA server certificate to the truststore for each server. They share the same CA and so I used the same certificate in each truststore. First, I am not sure why, but, NiFi did not like using port 636 for LDAPS, so I set it up to use 3269 instead and the SAN error went away. Everything I tried prior did not resolve the error, it would give me an error that it couldn't find a SAN with my.network.com:636 along with partial LDAP result not being able to find my.network.com, which didn't make sense because all of the troubleshooting I did would come back good. I could even resolve SSL using my key entry from my truststore. Once I had it up and working after that, I had to figure out why the buckets weren't loading. So I combed through a bunch of posts and found one that you wrote to someone having a similar issue and mentions the node needs to exist in NiFi-Registry. So, I added the node as "CN=node.hostname.com" (how I have it on the certificate) as a user account in NiFi Registry with the ability to read buckets and proxy user requests and bam buckets showed up. Seems like everything is working great now. I appreciate your help.

Sorry I haven't responded I've been busy working on this and can still say I haven't gotten it working. Not sure what the problem is that I'm having. I even spun up a bran new Linux Server and put NiFi and NiFi Registry on the same server. Can't even NiFi to start with the certificates I've provided it. All I receive is: ==> nifi-bootstrap.log <== 2023-08-18 16:34:30,290 ERROR [NiFi logging handler] org.apache.nifi.StdErr Failed to start web server: Error creating bean with name 'niFiWebApiConfiguration': BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.security.config.annotation.method.configuration.PrePostMethodSecurityConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.apache.nifi.web.security.configuration.AuthenticationSecurityConfiguration': Unsatisfied dependency expressed through constructor parameter 2; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'authorizer': FactoryBean threw exception on object creation; nested exception is org.springframework.ldap.PartialResultException: nested exception is javax.naming.PartialResultException [Root exception is javax.naming.CommunicationException: my.network.com:636 [Root exception is javax.net.ssl.SSLHandshakeException: No subject alternative DNS name matching my.network.com found.]] Not really sure it is as difficult to do this as I am making it out to be but I can say it's frustrating. If there are any guides that show step-by-step how to setup SSL with LDAPS authentication (not using any user certificates or requiring browsers to import their certificates) I'd appreciate it. Everything I can find is either setting it up with Ranger, Ambari, or using standalone certificates.

@MattWho Thanks for that information, I think I have it partially figured out now. We only have 1 CA, so it is easier for me to sign certificates as needed while I work through this. So far this is what has been done: Each Server (NiFi and NiFi Registry) using Keystore Explorer, I generated a keypair in the Keyststore with the required extensions (ClientAuth, ServerAuth & SANs) Created a CSR and had it signed by the CA. Imported the CA reply back into the Keystore with the full chain In the Truststore, I imported the root certificate Each server has LDAPS authentication setup, with the same default admin account that is able to login using it's AD credentials Added the NiFi server to authorizations.xml for Node 1 using the full DN from AD There is still something I am struggling with though: The only way the NiFi and NiFi-Registry will authenticate with each other is through a mutual TLS exchange. The NiFi certificate DN(s) will need to be authorized within your NiFi-Registry and so will your NiFi user. The NiFi host(s) will proxy requests to NiFi-Registry on behalf of the authenticated user in NIFi. Even though the NiFi is acting as a proxy, the user will still need be properly authorized as the results form the proxy request will be for only the buckets and flows for which the proxied user is authorized against. How would I go about doing this? I've tried importing each server's certificate into the others truststore but I started receiving errors about certificate path not being found and the most recent error is certificate_unknown.
