  I would suggest updating to at least 2.2.10.  It will be compatible with the 2.1.12 configuration files, and it contains a number of bug fixes.

  This isn't generally possible.

  DNS is assigned via DHCP.  RADIUS just returns yes/no for network access, and things like VLAN information.

  Think of it this way: the RADIUS Access-Accept is a message to the NAS, telling the NAS what to do.  The end-user machine doesn't see any of that.

  DHCP is a message to the end-user system.  So that's where DNS assignment goes.
