RADIUS login as wrong radius_user

I am testing radius authentication for vyos 1.2.7.
In this time, I found a unpredictable result.
I wanted to login user as shakapon, but in fact I logined as radius_user.

It’s my log.

shakapon@LAB-OAM:~$ ssh shakapon@
Welcome to VyOS
shakapon@’s password:
Creating directory ‘/home/shakapon’.
Linux vyos 5.10.28-amd64-vyos #1 SMP Fri Apr 9 13:46:54 UTC 2021 x86_64

I expected to login user as shakapon, but I logined as radius_user.
Next, I opened new terminal, and I also login as shkapon. In this case, I could login as shakapon.

This is my VyOS Configuration.

set interfaces ethernet eth0 address ‘’
set interfaces ethernet eth0 description ‘Out-Of-Band Management’
set interfaces ethernet eth0 vrf ‘Mgmt’
set vrf name Mgmt table ‘100’
set system login radius server key ‘XXXXXXXX’
set system login radius vrf ‘Mgmt’
set service ssh port ‘22’
set service ssh vrf ‘Mgmt’

My radius Server is freeradius 3.0.20 on Ubuntu 20.04.

I cannot understand thise behavior.
I want always to login by shakapon as shakapon.

Hi @Kensaku,

the CLI configuration you shared with us and debug output is not VyOS 1.2.7 - the output indicates Kernel 5.10 which is only found in the current development tree VyOS 1.4, so this is clearly a bug.
