Sorry I was misunderstanding, this is exactly what I have seen.

Yes, I think TAF is what I'm looking for.

The ExampleThr.pl as provided by dazuko.tar.gz works fine. But I noticed
the Obj.pm is not able to register "TRUST_REQUEST" in sub AccessMask
because the name of the variable does not start with "DAZUKO_ON_"

Obj.pm (line 256)
$id = 'DAZUKO_ON_' . uc($id);
$id = '$Dazuko::IO::' . $id;

In addition to that, "TRUST_REQUEST" is not known in IO.pm.

As workaround I calculate the bitmask by myself and pass it as first
element of an array to sub AccessMask.

Thanks for your help
Thomas
