IKEv2-Connector

I'm trying to establish a VPN connection via IKEv2 and the authentication should make an AD.

In the USG an AAAServer ( ad ) was created.

Within Auth.method: created "auth_ad_administrators " and method: ad stored .

Within the ( ad ) also users are shown during "test", which works.

Within User/Group: ad-user_adminstrators, also here "testuser" is found during the test.

If I now in the configuration: VPN_Gateway

under Phase1, extended_Authenticaion_Protocol

Server_Mode: auth_ad_administrators

Allow_User: select ad-user_administrstrators.

Always comes AUTH fail!

what else am I doing wrong?

On the windows_server, I see no entry in the "event log".

Have you experienced this / how did you implement this
