the problem is, that it isn't possible to login via VPN to the server.

With the simple mode (SKIP) it works until the VPN_client says "performing Netware login"
After 2 Minutes I get the error-message "Netware login failed. User is not logged in to Netware"

The same happens if I try it with NMAS+NDS (ike-mode)

If I try certificate-mode the error-message looks like this:
"An error was reported by the IKE-application. No matching authentication rule for the user certificate. Check with your administrator."

Can anybody help?

Even the simple method doesn't work. The login hangs and the NMAS-window for asking the password a second time doesn't come up.

Thanx for any advices.
