Okta LDAP integration

Has anyone out there successfully done an LDAP integration with LibreNMS and Okta?

I’ve gotten to the point with the configuration that LibreNMS successfully authenticates with Okta using the test script (auth_test.php -u username). I can tell because I get the Okta Verify 2FA prompt and when I approve it the process proceeds. If I put in a wrong password it throws “invalid credentials”.

But right after the authentication the script throws:

[email protected]# ./scripts/auth_test.php -u username
Authentication Method: ldap
Password:
Authenticate user :
Error: LibreNMS\Exceptions\AuthenticationException thrown!
Server is unwilling to perform

My config.php LDAP config:

Hi @jayscovill - This is kind of old, at this point. By any chance, have you had further success with implementing Okta?
