I am trying to get my Nifi standalone instance on my server and basically my requirement is LDAP authenitcation, for that i have read some documents and found need to setup SSL first so i have followed this link but i am getting the below error.

and my authorizers.xml

kindly have a look and advice.

	<authorizer>
        <identifier>file-provider</identifier>
        <class>org.apache.nifi.authorization.FileAuthorizer</class>
        <property name="Authorizations File">./conf/authorizations.xml</property>
        <property name="Users File">./conf/users.xml</property>
        <property name="Initial Admin Identity">"EMAILADDRESS=07anis@gmail.com,CN=admin,OU=EDM,O=XXX,L=HK,ST=HK,C=HK"</property>
        <property name="Legacy Authorized Users File"></property>
        <!-- Provide the identity (typically a DN) of each node when clustered, see above description of Node Identity.
        <property name="Node Identity 1"></property>

Try the following...

  • Stop your NiFi
  • Delete users.xml and authorizations.xml
  • Edit authorizers.xml so that the "Initial Admin Identity" matches exactly what see in your logs, notice yours has no spaces and the logs do have spaces
  • Start again

@Anishkumar Valsalam

The log you provided shows that user authentication is successful. What is failing is the users authorization inside NiFi. When setting up NiFi securely for the first time (enable SSL), you need to provide an "Initial Admin Identity". The Identity provided here will be used to seed the admin related access policies (Authorizations) within NiFi which will give that user the ability to access the UI.

The issue you are running in to is that what your LDAP has returned and what you have configured in your authorizers.xml file do not match exactly.

Configured value: EMAILADDRESS=07anis@gmail.com,CN=admin,OU=EDM,O=XXX,L=HK,ST=HK,C=HK

LDAP value: EMAILADDRESS=07anis@gmail.com, CN=admin, OU=EDM, O=XXX, L=HK, ST=HK, C=HK

These are case sensitive and spaces do count.

You cannot simply update the authorizers.xml config file to resolve your issue. When NiFi is started securely for the first time, users.xml and authorizations.xml files are generated based on the configs in the authorizers.xml file. Subsequent restarts of NiFi will not trigger a modification or re-creation of these files if they already exist. So to correct your issue, you will need to correct your "Initial Admin Identity" configuration so it matches what is being returned by LDAP, remove the existing users.xml and authorizations.xml files and then restart so they get created with the correct value/user identity.

Once you have gained access to your NiFi UI, you can add additional users and set authorizations for those users directly form the UI.

Thanks,

Matt
