We are trying to install Nagios XI on RHEL 9. We imported the backup from our current production instance and i can verify all the data is present. Everything is up and running as expected for us except the LDAP integration. I am able to login as nagiosadmin user but none of the LDAP users are able to login.

If I run a local ldapsearch command on the new machine, I can fetch user details properly. But LDAP based authentication is not working from Nagios XI UI.

I tailed the logs files also and do not see any error. tail -f /var/log/httpd/*

More information: I have followed all the steps mentioned on this article and nothing worked: Nagios XI - Can’t Log Into The Web Interface

I need some help in finding out how to test/fix the LDAP integration. Also if there is a different file location I need to check to find the correct error.

Appreciate any help.

Thanks

Thank you for the quick response. I tried that page as well and it did not print any additional debug information. That's why I am curious to know if I am looking at the wrong log file location.

Code: Select all

Open the file in vi by executing the following command:

/usr/local/nagiosxi/html/includes/components/ldap_ad_integration/ldap_ad_integration.inc.php
Make the change as per the following example:

function create_auth_conn_obj($server_id='')
{
    ldap_set_option(NULL, LDAP_OPT_DEBUG_LEVEL, 7);
    // Get our settings

One thing that I sometimes forget is that there's a script that needs to be run if the OS version is changed after a restore from backup. I seem to recall that it's mentioned in the backup/restore doc.

Yes, I ran that script as well. Its the restore_repair.sh script.
