Team,
 
NiFi secured cluster throws below error with wildcarded self-signed standalone 
certificate.  Just a brief background, we are deploying nifi in Kubernetes  
where we have to use wildcarded certificates. Till nifi 1.6.0, it was working 
fine.
Also I tried bringing up NiFi in linux VM in secured cluster mode with 
wildcarded certs, I am getting same error.
 
Toolkit command to generate certs:
bin/tls-toolkit.sh standalone -n 
'*.mynifi-nifi-headless.default.svc.cluster.local’ -C 'CN=admin, OU=NIFI' -o 
<targetfolder>

Please help me in resolving this.
 
Note: Same certificates is working for single mode setup.
