Can't get AAA Server -> Active Directory to work
I'm trying to set up AD user validation for SSL VPN connections.
I have earlier succeeded this on a VPN50, and a Windows SBS connected to same subnet, if that matters.
Now I'm trying to set up a VPN100 located at our office location, to validate users on a Windows Server 2016 DC, located at our external hosting partner.
I have filled in server address (primary DC IP), backup server address (backup DC IP), Base DN, Bind DN and password, but when using the configuration validation option in the bottom, I reciewe a "Wrong IP or Port" as result.
As I can identify, the default port (389) has not been changed on the DC.
Before I suggest that something must be wrong at our hosting partner, I would like to be quite sure, that I have made the configuration proper.
When looking the log right after performing the "configuration validation", I'm a little surprised that nothing seems to be logged in connection with the validation. Shouldn't I see something?
Every suggestions on what could be wrong appreciated.
