Review and update the location of the keystores and truststores, as needed.
Confirm that NiFi is allowed to auto-generate node identities. Set the prefix and suffix to values used in NiFi CA. (NOTE, ensure suffix that starts with comma has a space. Known issue exist for NiFi CA where space isn’t allowed after comma). Also ensure that it is aligned with a defined user group provider (by default this is the default file-user-group-provider)
- You must ensure that any suffix starting with a comma includes a trailing space.
- Verify that the suffix is aligned with a defined user group provider. By default, file-user-group-provideris specified.

If you are using Client Certificates for authentication and user authorization, restart the service and log in with the Initial Admin Certificate. If you need to create a client certificate see Get Client Certificates for Authentication.
If you are integrating with Kerberos or LDAP, continue with further configuration defined below.
