Perhaps you should pass the -h and provide a host for ldapmodify to connect to.

Instead of running ps in a while loop, you're better off running slapd in debug 
mode (because, then, you can actually see if something is happening) Here's a 
man page on slapd... http://linux.die.net/man/8/slapd

That being said, I find that it's nice to know all your ldap commands but I 
find it much easier to use phpldapadmin. 
(http://phpldapadmin.sourceforge.net/wiki/index.php/Main_Page)

Works great and never has any issues.

Subject: [Ltb-users] ldapmodify fails with 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.
