(RADIATOR) Question on PreHandlerHook

[Hugh Irvine]

Hello Oscar -

You should use "changeUserName()".

	${$_[0]}->changeUserName("new-test-value");

See the code in Radius/Radius.pm->changeUserName().

This is because Radiator does some caching of the username internally.

regards

Hugh

NB: have you included a copy of your configuration file (no secrets),
together with a trace 4 debug showing what is happening?
