Can't contact LDAP server
Posted: Tue Jan 30, 2024 5:05 pm
Howdy,
We enabled new AD GPO settings for LDAP channel binding and LDAP signing. I added the CA cert and configured our XI server for the new security and it works. I can't get the LS server to allow logins. The error is: "Can't contact LDAP server." The settings and cert are the same for the LS & XI servers.
I'd appreciate any help you can provide! Thanks!

Which version of Nagios Log Server are you using?
Here's an LDAP Troubleshooting document that we provide:

It's difficult to provide a definitive solution

As a follow up, can you use something like wireshark, or tcpdump to capture traffic going between your log server and the LDAP server? They'll be communicating on TCP port 389 or 636.
If your log server version is new enough, we've made some big improvements in the logging of LDAP problems, so if you're not on the latest version, I highly recommend moving toward it.
