Cause: Microsoft Windows Vista (TM) enforces the use of MS-CHAPv2 authentication. The default setting for the Steel Belted RADIUS Server does not support this.
Fix: Go to the “Users” page on the Steel Belted RADIUS Server, select the User that you wish to change to support MS-CHAPv2 and add the following two attributes: MS-MPPE-Recv-Key / MS-MPPE-Send-Key and Save the change.
Alternatively you can set up a “Profile” that contains these two Attributes and point any number of Users to the Profile. Do not add the Attribute MS-CHAP2-Success with a hard-coded value as the Steel Belted RADIUS server generates it correctly by default with a dynamic value which is checked by the X-famiy device.
