Sorry, I should have been more specific…I already have other apps using ldap with tls hitting the server and they work…so I am confident my AD server is properly configured.  I work a lot with ldap and I often find that some apps that integrate with ldap and tls get picky about the cert..thats why I think it might be the fact that I am using a self signed cert (which is common on AD servers).

 

Usually, there is a way to tell the application “ignore the fact that it is self signed, accept it anyway”

looks like you need to enable tls for ad to start listing for ldaps

 

no experience just a quick search.

Describes how to enable LDAP over SSL with a third-party certification authority.

Subject: [Observium] LDAP auth to MS AD with TLS Self Signed Cert

 

Hi,

  I have ldap auth working mostly, if I set tls to false, I can authenticate.  However, I want to be secure and when I enable tls, I get a debug error that says:

 

Error binding to LDAP server: servername.local: Can’t contact LDAP server

 

I am guessing the issue is the self signed cert that my server is using.

 

My question is…how do I configure Observium to accept self signed certs for ldap?

 

thanks

 

Tony
