Issue/Introduction

We're running running an AdminUI, when we try to import a simple
certificate, AdminUI reports an error :

Error: System error while attempting to import: One or more
exceptions trying to commit keystore changes. Please consult the logs.

Cause

Looking at the CDS log and the AdminUI log, we see that already a
certificate with the same subject exists :

cds.log 

  [Apr 23 2019 10:23:02,060] CertificateDataStore [ERROR] 
  CertificateDataStoreImpl.addCertificateToDB(): The certificate 
  already exists in the Certificate Data Store with alias 
  "my_test_sign". Cert Subject: 
  CN=mytest,O=sign,ST=myState,C=myCountry Cert Serial Number: 00 

server.log

  alias my_test_sign_new.

  not add certificate 'my_test_sign_new' (check logs for reason) 
 

Environment

Component:

Resolution

In the AdminUI, remove the old certificate. Then add the new
certificate.
