LDAP Authentication Plugin

The LDAP Authentication plugin adds LDAP Bind Authentication to your APIs, with username and password protection. Give it a try and discuss it here!

LDAP Authentication plugin documentation

I am looking for some help setting up LDAP plugin. I set up a local LDAP server and whilst I can confirm a valid account with ldapsearch, using those same settings on the kong plugin always results in “Invalid authentication details”. so my first specific question is - where does the LDAP plugin log to? I cannot find any entries in the nginx logs or in the kong log .

where does the LDAP plugin log to?

Hi! The ldap-auth plugin logs to the nginx logs as usual (look for [ldap-auth] in the logs). You may also want to raise the log_level in kong.conf to “debug” for troubleshooting, in that case it should log all authentication attempts.

Kindly mention the steps to configure ldap auth plugin.
I am stuck, not able to implement

Hi
Sharing the same issue with the ldap auth plugin : I can play successfully many ldapsearch commands using the same parameters than the one I give to the plugin, but protecting a route with ldap-auth systematically returns
{
“message”: “Invalid authentication credentials”
}
Nothing in kong logs except :
2019/03/24 17:27:45 [error] 36#0: *597859 [kong] access.lua:88 [ldap-auth]
Error: The supplied credential is invalid.
Details: , client: 172.19.0.1, server: kong, request: “GET /joiningUsers HTTP/1.1”, host: “localhost:8000”
172.19.0.1 - - [24/Mar/2019:17:27:45 +0000] “GET /joiningUsers HTTP/1.1” 403 48 “-” “PostmanRuntime/7.6.1”
I am also not able to see anything going to the LDAP server…
Any help would be appreciated starting from information on how to get more meaningful logs…
Best regards

I am done with LDAP authentication.
As you can see in attached screen shot.

Just add the api in kong, On the LDAP plugin and Send a authorization header as shown in Image.
Authorization header is consist of username and password in base64(username:password) encrypted format.
