OpenLDAP slapd problems - ldap_result: Can't contact LDAP server (-1) --- Low Sensitivity/Aerospace Internal Use Only

Low Sensitivity/Aerospace Internal Use
Only

Working on a CentOS-6.5 server, running LTB Project's  slapd-2.4.38.

Someone suggested I implement a cn=admin,cn=config for a cn=config setup.
 (I don't know how to technically word that).


Anyway, I need to make TLS-related changes and was told to do the following
command: 

ldapmodify  -x -D "cn=admin,cn=config"   -W  -d
256

...then at the blank line type the following, each on a single line:

Dn:                    
                 cn=config
Changetype:                
     modify 
Add:                    
                 olcTLSCipherSuite
OlcTLSCipherSuite:        HIGH:MEDIUM+TLSv1+SSLv3
<CTRL-D> 


I have been getting an error reponse of: 
ldap_result:  Can't contact LDAP server (-1)

This __ONLY__ occurs after I hit <CTRL-D>, not before.  Yes,
the daemon, slapd, is actually running, but after this failure it abruptly
stops.  I know this because in a separate terminal on the same system,
I am running a while-loop with a ps -e | grep slapd in it.


Please note the "-x" option according to the man page for ldapmodify
is supposed to Use simple authentication instead of SASL.


Thank you all for your help, hopefully you can: 

1) tell me what this error means, and 
2) how to fix my problem so that I can complete the olcTLSxxxx changes
I need to implement.
