I’ve got AD authentication working on our other LibreNMS server which is in another domain, but I can’t get this new instance of LibreNMS working in this other domain.

Is there a log file that might give me a hint to the issue?

I’ve already ran apt-get install php-ldap

This it roughly what my config.php looks like:
#$config['auth_mechanism'] = 'active_directory';
#$config['auth_ad_url'] = 'ldap://';    // Set server(s), space separated. Prefix with ldaps:// for ssl
#$config['auth_ad_domain'] = '';
#$config['auth_ad_base_dn'] = 'dc=thisdomain,dc=com';         // groups and users must be under this dn
#$config['auth_ad_check_certificates'] = false;             // require a valid ssl certificate
#$config['auth_ad_binduser'] = '[email protected]';          // bind user (non-admin)
#$config['auth_ad_bindpassword'] = 'myadpassword';      // bind password
#$config['auth_ad_timeout'] = 5;                           // time to wait before giving up (or trying the next server)
#$config['auth_ad_debug'] = false;                         // enable for verbose debug messages
#$config['active_directory']['users_purge'] = 30;          // purge users who haven't logged in for 30 days.
#$config['auth_ad_require_groupmembership'] = true;        // false: allow all users to auth level 0
#$config['auth_ad_groups']['Admin-LibrenmsAdmins']['level'] = 10; // set the "AD AdminGroup" group to admin level
#$config['auth_ad_groups']['Admin-LibrenmsUsers']['level'] = 5;   // set the "AD UserGroup" group to global read only level
