Debug Glassfish file Authentication

Glassfish basic file authentication fails me with:

message Access to the requested resource has been denied

de开发者_开发问答scription Access to the specified resource (Access to the requested resource has been denied) has been forbidden.

I think I did everything right but obviously I did not. Has anybody got any ideas on how to debug the authentication process?

After more experimenting I found that the following line in config\logging.properties gives a few extra informations:

javax.enterprise.system.core.security.level=FINEST

Still debugging authentication is a pain and if someone knows how to get more informations I would be grateful.
