L2TP VPN Client-to-Site "Wrong Base DN or Bind DN" test error

methesrl

Hello everyone,

I have multiple Zyxel USG Flex 100 in multiple sites and each of those has a L2TP VPN Client-to-Site configuration with AD login.

They all work wonderfully, except this last one..

I configured this one as any other one but every time I test it from the AAA Server it gives me the error "Wrong Base DN or Bind DN".

I looked over different guides found here in the community and my setup seems exactly as indicated.

Base DN: DC=comune,DC=calasetta

Bind DN: CN=Administrator,CN=Users,DC=comune,DC=calasetta

Here are some screenshot of the AAA Server setup:

Error testing:

If you need any other info or screen I'll send them right away.

Thanks in advance.

Based on the error message, it seems the content of base/bind BN is false. Could you check on the settings again? or show me the content, thanks.
Moreover, can you also try again by enabling "Use SSL" in the settings?
