Confusion about LDAP setup

Installation
1

Hi everyone,

I am trying to setup LDAP in our local discourse to use the LDAP server of our university. I got a working configuration of another app from a colleague and tried to adapt it to use it with the discourse LDAP plugin (GitHub - jonmbake/discourse-ldap-auth: Discourse plugin to enable LDAP/Active Directory authentication.) but I cannot get it right. Presumably I got the syntax or attribute names wrong. Unfortunately I have no experience using LDAP.
The connection to the server seems to work but I always get “(ldap) Authentication failure! invalid_credentials encountered.”
Below you find the current discourse LDAP configuration as well as the working configuration of the other app.

Many thanks for your help in advance!

Best,
Marco

Ok, our computing center advised me not to use LDAP and instead use their OAuth2 IAM. I will try that.
Thank you anyway!
