Running OpenVPN 2.3.10 on Ubuntu 16.04 using a working configuration with only 
the "script-security" and "client-connect" lines added.  Starting the OpenVPN 
server with systemctl starts it successfully and a client can connect but the 
client-connect script doesn't run and no error is reported in the log.  
Stopping the daemon with systemctl and starting it manually with the below 
parameters doesn't allow a client to connect, the log shows:
            CRL: cannot read: rw-crl.pem            TLS_ERROR: BIO read 
tls_read_plaintext error: ... ssl3_get_client_certificate:certificate verify 
failed            TLS Error: TLS object -> incoming plaintext read error        
    TLS Error: TLS handshake failed
Starting it manually with the *** only *** change being the removal of the 
--daemon parameter produces a totally working system.  Any idea what is wrong 
or suggestions?
(The following obtained using 'egrep -v "^$|^#|^;" server.conf', it was put 
into a file and the following two vi commands used to put it into the proper 
format before adding /usr/sbin/openvpn and --daemon at the front     :%s/^/--   
 and :%s/\n/ /      )
