I am trying to connect with Cisco VPN Client using MS Radius, but appears the message : Authentication reject: unspecified.
I tried also use the option [x] Do not required pre-autentication, but don´t working of guide cisco_vpn_msradius.pdf - troubleshooting.
In VPN Concentrator - Administration the test of ping is ok to MS Radius Server.
I see the logs and the only different thing that appear is the payload error.
Thanks a lot
Can you check that your group has PAP as the authentication protocol under the PPP attributes? As well if you have som logs on the event viewer of the windows box share them here.
