LDAPs and SSL Problem

Hi,

I tried to configure my LDAP authentification using a CA certificate.

Test Connectivity is successful also Test User credentials.

Before my VPN worked fine. I deleted my user (first from group) then I recreated it. No problem I can browse LDAP.

I didn't change anything to my client. I waited a few minute sbefore trying. But everytime it fails at 80% and looking at logs : Events,  VPn it says :

sslvpn_login_unknown_user

Tried on another Fortinet, same result. What am I doing wrong ?

Not e: I followed

https://docs.fortinet.com/document/fortigate/6.2.2/cookbook/688719/ssl-vpn-with-ldap-user-password-renew

https://www.infosecmonkey.com/2019/04/20/secure-ldap-and-ad-password-change-via-forticlient/

Thanks !
