I have Fedora Directory Server with SSL running on my Linux Machine. I can see th output:
[root@389-ds ~]# nmap -vv localhost
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2010-01-10 01:26 IST
Initiating SYN Stealth Scan against localhost.localdomain (127.0.0.1) [1680 ports] at 01:26
Discovered open port 22/tcp on 127.0.0.1
Discovered open port 636/tcp on 127.0.0.1
The SYN Stealth Scan took 0.21s to scan 1680 total ports.
Host localhost.localdomain (127.0.0.1) appears to be up ... good.
Interesting ports on localhost.localdomain (127.0.0.1):
Not shown: 1678 closed ports
PORT STATE SERVICE
22/tcp open ssh
636/tcp open ldapssl
Nmap finished: 1 IP address (1 host up) scanned in 0.344 seconds
Raw packets sent: 1680 (73.920KB) | Rcvd: 3362 (141.208KB)
This shows that 636 port is open.But When I am attempting to this Linux Server from one of Windows Desktop it says "LDAP is Down".
I selected LDAPv3 and LDAPv3, hostname and SSL/TLS tried fetching base DN but it dint work.
