Hi Thanks once again for all the advice :-)
Does anyone know if there some characters that are reserved i.e cannot be used in secret keys with a freeradius server. If so what are they? I've been experimenting with the radtest client and the freeradius server using local unix validation with interesting results. 1) If I use a secret key (16+ characters and the same key in both the radtest client and freeradius clients.conf) that contains pure alpha characters the key is accepted and authorisation is successful. 2) If I use a secret key (similar to the one set on the IAS server) containing characters such as $\[ then the key is rejected and authorisation is unsuccessful. I have tried enclosing the key in single and double quotes, but the key is still rejected. Hopefully getting nearer to a solution... Thanks very much Clive - List info/subscribe/unsubscribe?
