I believe that in your access policy provider, you need to change
<property name="User Group Provider">ldap-user-group-provider</property>
with
<property name="User Group Provider">composite-configurable-user-group-provider</property>

So that you have both the File and LDAP providers.

Be sure to remove /home/faureciarun/nifi-data/configuration-resources/users.xml on all nodes before restarting because once it's been generated with the initial users/identities, it's not updated on next restarts.

Hello Pierre.

 

https://gist.github.com/zorel/3655188026b0355c8860030932884fa9

 

I’ve tried to comment edge2 and 3, but I have now the error for edge1, which is the node I try to launch.

Hi Aurélien,

 

Based on the error, I'm pretty sure it's located in the authorizers.xml file. Do you mind sharing it (after removing anything sensitive)?

No need to add the nodes in the LDAP and it's definitely not related to keystores.

Hello.

I'm struggling to configure the very first node of my 3 nodes nifi 1.8.0 cluster.

I've used the toolkit to create the jks:
bin/tls-toolkit.sh standalone -n 'par01prdedge[1-3].fqdn' -C "CN=admin,OU=nifi" -c "par01prdedge1" -d 3650 -o ~/nifi-data/toolkit -O

I have then 3 directories, with a keystore (with Owner: CN=par01prdedge1.fqdn), a truststore and nifi.properties.
I've doublechecked spaces & uppercases in the DN, and it's ok everywhere.

Configured login provider to use the ldap configuration (which is working on other nifi instance)
Configure authorizers.xml to use:
- A ldap group provider
- A file user group provider with initial users identity for the 3 nodes of cluster
- A composite user group provider to use the 2 previous user group providers
- A file access policy with 3 nodes identity and the initial admin identity

I don't have ldap entries for my nodes, and I get the following error when I run the server on edge1.
Caused by: org.apache.nifi.authorization.exception.AuthorizerCreationException: Unable to locate node CN=par01prdedge2.fqdn, OU=NIFI to seed policies.
        at org.apache.nifi.authorization.FileAccessPolicyProvider.populateNodes(FileAccessPolicyProvider.java:639)

It seems to find correctly is own identity, but not identity of others nodes.

I wonder how nifi locate node identity, do I have to create an entry for the nodes in the LDAP? I'd like to avoid it. DO I have to "merge" the jks of the 3 nodes?

I wonder if I should use the tls-toolkit in server mode?

I've read blogs post from
https://pierrevillard.com/2016/11/29/apache-nifi-1-1-0-secured-cluster-setup/
https://bryanbende.com/development/2018/10/23/apache-nifi-secure-cluster-setup (but this one does not document how to create the jks)
with no luck, still wonder where is the problem.

Thanks for any pointer.
