(RADIATOR) Login Banner being sent as Username?

[Ben Ragg]

HI there,

We've been running Radiator for a long time as a Radius server, but 
switched to also using it for TACACs after our last TACACs server 
decided to visit that data centre in the sky.

Since moving we're seeing a lot of authentication requests coming 
through with parts of the login banner and other random characters.

Quick snippet...

such user
Thu May 24 12:27:35 2007: INFO: Access rejected for o memory for 32 
bytes: No such user


...has anyone who has been using Radiator as a TACACs host noticed this? 
All the devices are various models of Cisco gear.

Cheers,
Ben
