'csync2 -x' reports wrong SSL X509 certificate; while trying to remove the old certificate leads to 'Local csync2 database not found' error

csync2 -x is used to synchronize files among nodes within a cluster. If for some reason peer node was re-created but still have the same hostname, running 'csync2 -x' reports following error:
    # csync2 -x
  'Peer did provide a wrong SSL X509 certificate'

    Normal procedure to remedy this issue is to run `csync2-rm-ssl-cert $PEERNAME` to remove old entries.  
    However, following error could be seen:
  HOST:~ # csync2-rm-ssl-cert HOST2
  Local csync2 database (/var/lib/csync2/HOST1.db3) not found.


    Either using the following command to remove the old entry :(NOTE: for SLES12, VERSION=3)
    # echo "DELETE FROM x509_cert WHERE peername='HOST2';" |sqlite${VERSION} /var/lib/csync2/$(echo $HOSTNAME | tr [:upper:] [:lower:]).db${VERSION}
    or create a symbol link in /var/lib/csync2 directory as
    # ln -s host1.db3 HOST1.db3


    When csync2 creates local database it uses all lower-case characters. If hostname contains upper-case letter, the discrepancy would cause this database not found error.

    Following command can be used to list all the recorded `peername's:
  # echo "SELECT peername FROM x509_cert;" |sqlite${VERSION} /var/lib/csync2/$(echo $HOSTNAME | tr [:upper:] [:lower:]).db${VERSION}
