NIFI Unable to locate initial admin CN=admin,OU=people to seed policies

New Contributor

Hello!

I installed Nifi, Nifi toolkit.

I have an error "Unknown user with identity 'CN=admin, OU=people, DC=nifi, DC=com'. Contact the system administrator." or

"Unable to locate initial admin CN=admin,OU=people,DC=nifi,DC=com to seed policies".

Your nifi.properties file is configured to look for an Authoriuzer with the identifier Managed-authorizer.

nifi.security.user.authorizer=managed-authorizer

The shared authorizers.xml does not contain a "managed-authorizer".

If you want to use the "file-provider" you need to update your nifi.properties file.

-

I also see that you are using ldap-provider for logging in to your NiFi. It is configured with:

<propertyname="Identity Strategy">USE_USERNAME</property>

This means that whatever string the user enters in the username login box will be parsed by any configured Identity.mapping.pattens configured in nifi.properties file and then resulting value string passed to authorizer.

-

So even once you fix your auithorizer.xml or nifi.properties file, You are likely going to send "admin" to your authorizer rather then the admin user's full DN.
