Cut domain from username

hi,

okay, so you can remove realms by handling them - but as you say, if its
not defined in your proxy list and its just random, that method cannot be
used.
luckily you can use regex in proxy.conf to handle anything thrown at you -
OR you can populate Stripped-User-Name yourself by using some unlang
in the inner-tunnel tunnel authorise section , check for presence of @ and
return the %{1} component.
