Want to Use SSL i.e., Organization Provided Certs for New NiFi Cluster Users

Labels:

Created ‎04-08-2023 10:05 AM

Hello, I have a 3 node NiFi Cluster up and running.  The Initial Admin User is able now to successfully log into the NiFi cluster.  

 

I would now like to add new users to the NiFi cluster and SSL i.e., signed PKI certs for each user as the basis for these users to gain access to NiFi.

 

I do not want to use LDAP, I am in an environment that will require use of PKI certs for access to NiFi.

 

Can someone provide a prescriptive set of steps I can follow to successfully use PKI certs/SSL as a means of providing access to new NiFi cluster users and specifically, how do I add new users?

 

I would think the process of creating new users and using SSL would be explained explicitly.  

 

Can someone help me with this?

 

VR,

 

Dave

Your corporate PKI certs are just certs signed by your corporate signing authority.  So really nothing needs to change in the configuration of your NiFi.  However, you will need to add your corporate signing authorities public certificate to the truststore.jks used by your NiFi.

When you access the NiFi UI a mutual TLS exchange occurs.  You client (browser) initiates the connection with a client Hello to which the server will respond with a server Hello.  In that server hello a list of certificate authorities (comes from CAs in the NiFi truststore) will be provided to back to the client.   This tells the client that it will only accept a client certificate signed by one of those authorities.  If the client (your browser) has a pki certificate loaded that was signed by one of those trusted authorities, that client certificate can be used to complete the mutual TLS exchange.  Much more happens in the Mutual TLS client server handshake, but i'll just stick to the certificate specifics here.

NiFi does nothing out of spec when it comes to certificates and NiFi has nothing to do with creating users.  You can create your own self signed certificates created via command line tools, use a public signing authority to create signed certificates, or in your case use your corporate signing authority to create certificates.  A java keystore is nothing more than a container that can hold 1 too many certificates.

Only requirement NiFi has with regards to the keystore it that it contains only 1 PrivateKeyEntry (private cert).  The truststore (just another keystore) can contain 1 too many trustedCertEntries (public certs) and often contains many public intermediate and root CAs.

@davehkd  It is difficult for me t say where your configuration has gone wrong with what has been shared
I would need to see your authorizers.xml.  

I see in your output mention of the SingleUserAuthorizer.  This authorizer does not support defining additional user for assigning policies.

What do you have configured in your nifi.properties for these configuration lines:

nifi.security.user.authorizer
nifi.security.user.login.identity.provider

If either of these is using the "single-user-provider/authorizer", it is expected that you will not see users in the UI.

You'll need to use an authorizer that supports multi user setup like the https://nifi.apache.org/docs/nifi-docs/html/administration-guide.html#standardmanagedauthorizer.


since you are using user certificates for handling your user authentication. the nifi.security.user.login.identity.provider configuration property should be blank.

@davehkd 

1. You can't have multiple providers in the authorizers.xml.  You'll ned to comment out the "singleUserAuthorizer".
2. Your "managed authorizer is not correct, you are missing the class:

 

<authorizer>
        <identifier>managed-authorizer</identifier>
        <class>org.apache.nifi.authorization.StandardManagedAuthorizer</class>
        <property name="Access Policy Provider">file-access-policy-provider</property>
    </authorizer>

 

3. Your file-access-policy-providers configuration looks good here.
4. Your file-user-group-provider configuration is not correct, you are missing the line that defines where the users.xml file is to be created:

 

<userGroupProvider>
        <identifier>file-user-group-provider</identifier>
        <class>org.apache.nifi.authorization.FileUserGroupProvider</class>
        <property name="Users File">./conf/users.xml</property>
        <property name="Initial User Identity 1">CN=ec2-user</property>
        <property name="Initial User Identity 2">CN=nifi1, OU=NIFI</property>
        <property name="Initial User Identity 3">CN=nifi2, OU=NIFI</property>
        <property name="Initial User Identity 4">CN=nifi3, OU=NIFI</property>
</userGroupProvider>

 

 

Make sure that in your nifi.properties file, you have configured NiFi to use the managed authorizer:

nifi.security.user.authorizer=managed-authorizer


Make sure that in your nifi.properties, you do NOT have the following property configured to use the single-user-provider:

nifi.security.user.login.identity.provider=

Thanks for the reply Matt.

 

I followed the instructions per:  https://nifi.apache.org/docs/nifi-docs/html/walkthroughs.html#securing-nifi-with-provided-certificat...

 

Specifically, I followed the instructions for:  Creating and Securing a NiFi Cluster with the TLS Toolkit.

Per Step 1, I ran the optional command to execute all steps together using the the toolkit pattern syntax:

./bin/tls-toolkit.sh standalone - n 'node[1-3].nifi' -C 'CN=ec2-user' -c 'ca.nifi'

 

Per step 9, I updated the authorizers.xml file, in the <userGroupProvider> section, I added the line 

<property name="Initial User Identity 1">CN=ec2-user</property>

In the <accessPolicyProvider> section, I updated the file as described.  Regarding the Initial Admin Identity, I updated the file as follows:

<property name="Initial Admin Identity">CN=ec2-user</property>

 

I copied the authorizers.xml file to all 3 nodes.

 

After starting nifi on all 3 nodes, I then access the GUI and select the imported certificate i.e., CN=ec2-user.p12 which I successfully imported, and I can successfully access the GUI.  

 

I see that on the upper right of the GUI screen, the the user is indicated as CN=ec2-user.  But, when I access the menu on the upper right of the screen, I do not receive the users option.

 

Can you help me determine why this option isn't available?   I am unclear, having followed the instructions per the walkthrough, why this

To add:  At step 13, per the walkthrough i.e., NiFi Cluster Using NiFi CA, as described, I stopped each of the nifi instances, i then deleted the authorizations.xml and users.xml file from each node in the nifi/conf directory, and then restarted each node.

 

And, then I logged onto the NiFi GUI, and still I do not see the users option in the menu...

 

i.e., I apparently do not have a a running cluster with permisisons....

 

Please help

Matt, I found this ticket:  NIFI 1.14: User policy is not showing on the GUI.  This is exactly the issue I am having.

I see that you recommended that he:  verify the configuration in the authorizers.xml file, remove the existing users.xml and authorizations.xml file and restart NiFi.

 

I took these steps several times and still the "Users" option does not appear in the menu.

An update:  So, after starting NiFi, i reviewed the logs in the nifi-user.log file.  

This is what was output:

Another update:

 

I looked in the authorizations.xml file and see that the user ec2-user has the following authorizations:

 

flow  action "R"

data/process-groups/ action "R"

data/process-groups action "W"

process-groups action "R"

process-groups action "W"

restricted-components "W"

tenants actions "R" and "W"

policies actions "R" and "W"

controller actions "R" and "W"

I changed the name of the nifi user from ec2-user to nifi thinking that perhaps the - was causing an issue.

 

Specifically, I generated the client certificate keystore from the client certificate and key using the following command:

openssl pkcs12 -export -out CN=nifi.p12 -inkey client.key -in client.pem

 

I then logged into the nifi gui and selected the certificate i.e., CN=nifi.p12.  And no luck, the users option is not available on the global menu.

 

Here is output from the nifi-users.log

@davehkd  It is difficult for me t say where your configuration has gone wrong with what has been shared
I would need to see your authorizers.xml.  

I see in your output mention of the SingleUserAuthorizer.  This authorizer does not support defining additional user for assigning policies.

What do you have configured in your nifi.properties for these configuration lines:

nifi.security.user.authorizer
nifi.security.user.login.identity.provider

If either of these is using the "single-user-provider/authorizer", it is expected that you will not see users in the UI.

You'll need to use an authorizer that supports multi user setup like the https://nifi.apache.org/docs/nifi-docs/html/administration-guide.html#standardmanagedauthorizer.


since you are using user certificates for handling your user authentication. the nifi.security.user.login.identity.provider configuration property should be blank.

Thanks so much for your response Matt!

 

 

nifi.security.user.authorizer=single-user-authorizer

nifi.security.user.login.identity.provider=single-user-provider

 

I think I'm close.

 

I'll set to blank:  nifi.security.user.login.identity.provider

 

I'll read the link you provided but I assume that the nifi.security.user.authorizer needs to be set to the initial admin identity...

 

Thanks again for your input!
