AAA FreeRadius problem with IOS XR plateform

[Dhaf54134]

Hello Community,

to control access to routers in our Backbone, I decided to install a freeRadius Server

all thing are Ok with cisco IOS and IOS XE plateforme but I have an issue with IOS XR platforme.

I launched a debug in my FreeRadius Server when I was trying to connect to the IOS XR router, I noticed that  this string's added to the password account : "\000\005\004\003\002\001"

this's why the Radius server send an access-Reject

I don't Know why, I spent two days to debug this issue withou success.

Can anyone help me please ?
