I have been having the same problem as thread linuxquestions.org/questions/showthread.php?s=&threadid=296210
but, I do not have tls running and I still have the same problem.,

I have been trying to get LDAP to work on SUSE 9.2 Pro for 2 weeks. I installed it using the rpm from the install CD and did the current updates for SUSE bringing the OpenLDAP2 version up to 2.2.15-5.2. I have followed all the LDAP setup papers from several sites on the internet, but I still can not get SUSE 9.2 to see the LDAP server it is running. When I try to connect with the LDAP client or through user setup, I get the message "Connection to LDAP server can not be extablished. The LDAP server is running with no errors in the message log. I know I have to be missing something, but I do not know where. I have LDAP running on a SUSE 9 Enterprise Server with no problem. The Yast2 setup for the LDAP enterprise server did most of the work, but SUSE 9.2 does not have a LDAP server setup in it's Yast2.

Steps I followed to setup LDAP on SUSE 9.2 PRO.
Installed from RPM on CD, did updates from SUSE website for LDAP.

Edit the ldap.conf file with follows:

# LDAP Defaults
#

# See ldap.conf(5) for details
# This file should be world readable but not world writable.
#BASE dc=example, dc=com
#URI ldap://ldap.example.com ldap://ldap-master.example.com:666
#SIZELIMIT 12
#TIMELIMIT 15
#DEREF never
base dc=asi-web,dc=com
host 127.0.0.1

Edit slapd.conf with the following:

# See slapd.conf(5) for details on configuration options.

using command: ldapadd -x -D "cn=Manager,dc=asi-web,dc=com" -W -f setup.ldif.
Did not get any errors from this.
Started slapd.
The message log shows no errors when starting slapd.

ldapsearch -x gives me:

What am I missing?
Thanks,

On the client - what happens when you "telnet yourldapserverhost 389"?

Also post the entry from /etc/openldap/ldap.conf. This file is used when you run commandline like ldapsearch, ldapadd etc.

This is what I get when I telnet to 389

telnet 10.10.10.10.175 389
Trying 10.10.10.175
Connected to 10.10.10.175
Escape character is '^1'.
Connection closed by foreign host

Thanks,

I backup to SUSE version 9.1 and it cleared this problem for me.

Thanks,
