After having some packet traces done, what was revealed is that from a windows client running the softerra ldap browser, we could see the connection be established between client and server (syn, ack synack) client requests sending of data, and server resets/closes the connection, never sending any data, as I also saw with attempting to telnet to port 636 - connection is closed by remote host.
Regarding the question of is TLS enabled, if I understand the doc correctly, the answer is yes. With respect to the TLS_REQCERT never statement, I believe it was set this way because this was only intended to be a testing server.

I've been tasked with figuring out why a redhat 6.4 server w/openldap v2.4.23 is not accessible. This server is a test server. I have a production server that is working properly, and I've gone thru and compared config files, etc, but haven't found any differences.
I'm a newbie with this, so my understanding is still somewhat limited. Here's what I've done or checked so far:
- iptables is not running
- if I run netstat, I can see port 389/port 636 in listening state:
tcp 0 0 0.0.0.0:636 0.0.0.0:* LISTEN 5603/slapd tcp 0 0 0.0.0.0:389 0.0.0.0:* LISTEN 5603/slapd tcp 0 0 :::636 :::* LISTEN 5603/slapd tcp 0 0 :::389 :::* LISTEN 5603/slapd
I can telnet to port 389 on this server from another server, but not to port 636 - putty will throw back an immediate 'connection closed by remote host' message.
I'm not seeing any slapd related messages in /var/log/messages.
What else can I check on here?
Syslog
Thanks Chris
