[RADIATOR] laptop sending out wrong attribute

[Bao Tran]

Hi everyone, I'm new to this forum and of course new to linux:). 

I have a number of laptops on the new domain but unable to associate to the wireless network.

When I try to connect my laptop to our wireless network by entering the username e.g. jsmith, and the password.
Looking at the radius log below, my understanding is that he laptop unable to authenticate because the laptop sent the User-Name attribute to the radius server as " host/PC12.domainA.com.au" instead of username 'jsmith"

Is is possible to change that on radius? or I have to create a group policy to change it on the laptop?
