#12 Support Windows Groups for configuration

[jp10558]

Please consider adding support for windows groups as well as specific users in the XML config file for setting up specific capabilities.

I'd like to be able to set a local or domain group as the "user" in the XML file. I understand from our discussion that this would impact performance - I'd expect that the impact would not be a problem in our setting as we can wait a while, maybe a progress bar in the dialog while doing the lookup if it's going to be a while (10+ seconds)?
