Hi Matthew,

Thanks for the update. Yes the software of the Cisco is very old and cannot be updated.
The issue there is that was working very well before.

I need to split with "\000" ?

Looks like your NAS is broken. It's not calculating the length of the
User-Name attribute correctly and presumably leaking whatever memory
was after it.

It should be sending it with, in this case, length 10 and no NULL.

If there's no software update for the NAS to fix it then you may be
able to work around it by writing some unlang with a regex to chop it
down to the right length.
