When setting up LDAP Authentication between a SMA (Systems Management Appliance) and an LDAP server, there may be connectivity issues.
There are a few ways to test LDAP server availability and it would be best to run these tests inside the same subnet as the SMA.
-Any failures with tests run outside of the same subnet as the SMA may indicate network port issues.
-Any failures with tests run inside the same subnet as the SMA may indicate LDAP server issues.
The easiest tool to test an LDAP connection is telnet. Although it is not usually installed by default, the telnet client can be easily installed without the need for a reboot following this guide.
. Once telnet is installed, run this from a command prompt:
telnet server.domain.com 389 (636 if using secure LDAP) (substitute server.domain.com for the LDAP Server).
You can get more in-depth information using the cmd line tool portqry. This is a Microsoft tool and it can be downloaded here.
Once portqry is installed, navigate to the install portqry directory from a command prompt and run this command:
portqry -n myserver -p udp -e 389 (636 if using secure LDAP) (substitute myserver for the name of the LDAP server).
