FortiGate200F , firmware version 7.0.8, I need some hint.
1- So I configure an LDAP server on my Fortinet, used the "test" button with a username and password and it's working.
(Edit LDAP Server image : That "test user credentials" button is working.)
2- I configure a group (GUI : User & Authentification - User Groups), named GRVPNLDAP pointing to a LDAP group on Active Directory.
3- I then configure a remote VPN with GRVPNLDAP to authenticate with the IPSec Wizard, remote - native - Windows Native.
(VPN Creation Wizard image : We use this Wizard to create the new Remote VPN.)
4- I convert the new R100 IPSec Tunnel , so I can use a secondary IP address on the Wan interface.
5- When I test the VPN, In the Event VPN logs, I see : Pass1 ok Pass2 ok, then the connection closes.
6- I test/configure another Remote VPN, with the same settings, except with a local user, it works.
7- I test/configure a login for the Fortinet GUI that autenticate with GRVPNLDAP, it works.
What's not working here??? Can someone gives me some hints?
I will test this again on the next weekend (November 5 and 6, 2022) , and come back with my findings.
