Description
This article describes how to configure FortiAuthenticator so a remote LDAP administrator can log in to the FortiAuthenticator GUI using a mobile FortiToken code as Two-Factor Authentication.
Scope
FortiAuthenticator 6.4, FortiToken Mobile.
Solution
- Ensure the remote LDAP administrator exists in the FortiAuthenticator user database.
- Ensure the user has full Administrator permissions:
- Test a remote LDAP login to the FortiAuthenticator GUI using an administrator account.
The user will successfully log in to the FortiAuthenticator GUI. To verify, navigate to Logging -> Log Access -> Logs and https://fac-ip-or-fqdn/debug/radius for detailed radius authentication logs.
