Hi, Daniel,

thanks a lot for the quick answer and the sample code. I've done some more investigations trying to debug the users code.

This bit works fine for me and him. The initial creation of the client object works. The problem comes when you try to use it to actually do something with it, 
like listing the images, eg invoking describeImages with something like:
$VAR1 = {
          'Filter' => {
                        'FieldValue' => [],
                        'FieldType' => [
          'Owner' => '392941794136',
          'ImageId' => undef,
          'ExecutableBy' => undef
This throughs immediately the authentication error.

not really. econe.log only contains what I also see in the apache logs, basically the authentication error return. 

> 3. Did you activate the new AUTH driver in the oned.conf?
Initially yes, but then I switched it off to be sure it's not that. Same problem. 

Kind regards,
