virt-manager throws VIR_ERR_AUTH_FAILED

[pmueller]

Hello,

I can start libvirtd without error message, but when I try to start virt-manager I get the following output:

Then I get the following error on the console where I started libvirtd:

 # libvirtd --verbose

Do you have an idea what the problem might be?

Thanks,
