[RADIATOR] blank outer identity - best practice

[Hugh Irvine]

Hello Alexander -

Actually you can use any AuthBy module *except* AuthBy INTERNAL.

This is because the AuthBy INTERNAL doesn't do anything other than return a result.

Ie. it does not actually process a user, and hence does not contain the EAP plumbing.

regards

Hugh

NB: 

Have you read the reference manual ("doc/ref.html")?
Have you searched the mailing list archive (www.open.com.au/archives/radiator)?
Have you had a quick look on Google (www.google.com)?
Have you included a copy of your configuration file (no secrets), 
together with a trace 4 debug showing what is happening?
