SAP SSO (SNC) for ABAP - VPN problems?

Hi everyone,

we are using SAP SSO (SNC) for ABAP to Logon to our SAP Systems. In the internal Lan SAP SSO work's fine, but over VPN we have some problems with the SSO connection or the kerberos ticket. If you want to connect via VPN and SSO to a SAP System, you get this error:

GSS-API(maj): No valid credentials provided (or available)

GSS-API(maj): No Kerberos SSPI credentials available for requested nam

Could't acquire DEFAULT INITIATING credentials

In the following the steps to connect to our Company NETWORK via VPN:

1. Start Windows

2. Logon to Windows (without domain connection)

3. Start VPN and logon

4. Now you are in the internal lan and you have a connection to the domain

I understand, that we have no valid kerberos ticket on the workstation, but we have a valid domain connect. I should get a valid new kerberos ticket. I don't know where the Problem is in our system or company network. I hope you can help me, to sort this problem out.
