I am using hortonworks sandbox 2.4, While securing Nifi step_by_step, I used TinyCert to generate my own certificate authority and certificates and I download the client and server certificates in PKCS12 format. After that I created some changes in Nifi config --> nifi.properities as shown in the picture. Finally, I open the file authorized-users. xml, in the Nifi-conf directory and create an admin user based on the DN of the client certificate.
<user dn="CN=guest, OU=demo, O=Hortonworks, L=trichy, ST=tamilnadu, C=india">
I follow this link https://community.hortonworks.com/articles/886/securing-nifi-step-by-step.html.
While I run Nifi under localhost:9090 I got error as shown in the picture
