[Serusers] Authorization Problems with Radius.

[Ricardo Martinez]

Hi.
I'm new in SER, but i have followed all the instructions to install the
RADIUS interaction.  Now i have obtaining the nex error in the console debug
when a REGISTER message arrives to the SER.

 7(21063) check_nonce(): comparing
[4134bbc79ed1bc9d3f911cb33ff4c399d7cdea8c] and
[4134bbc79ed1bc9d3f911cb33ff4c399d7cdea8c]
 7(21063) radius_authorize_sterman(): Failure

In my radiusclient.cfg i have configured for authentication  localhost:1645.
In my Radius Server (Radiator) i'm not see any Radius message.

What is the problem?
Hope someone can help me

Thank in advance
BEst Regards
