Now, The Server works fine when I turn off the Radius plugin and enter the and enter stuff in the chap-secrets. This is the output of radisd -fX
Humm... have you checked possible error messages in /var/log/messages (where pppd and the radius plugin output by default) ?
I remember I had an equivalent problem once... could you check that your radiusclient on the VPN side has got the dictionary.microsoft file in its dictionary directory ?
Also remeber to add the following line at the end of your radiusclient 'dictionary' file: INCLUDE /path/to/dictionary/directory/dictionary.microsoft For your information: If you are using radiusclient, your dictionaries might be in /etc/radiusclient. If you are using radiusclient-ng, check the /usr/share/radiusclient-ng directory. HTH, Thibault
