Grafana Configuration
1

  • What Grafana version and what operating system are you using?
    v9.4.3

  • What are you trying to achieve?
    Configure LDAP with Active Directory

  • How are you trying to achieve it?
    via the ldap.toml file

  • What happened?
    I have set up security groups for LDAP access for Admins. Some members of this group can log in whereas others get “No teams found via LDAP”.

  • What did you expect to happen?
    All members of the security group to have Admin access

  • Can you copy/paste the configuration(s) that you are having problems with?

  • Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
    When I search for the LDAP user in Grafana LDAP section, I get “No teams found via LDAP”

  • Did you follow any online instructions? If so, what is the URL?
    No

I cannot find the difference in the user accounts who are able to login vs denied login. I tried copying a user account who is able to login but no luck.

Fix: I gave the bind_dn AD user “Domain Admin” rights and it started working. Will look into the most restrictive permissions instead.
