Determining the user in a .tpl?

Shell

I am trying to set an extended attribute for the author of a DCR when they preview/generate so that whoever is creating/changing the content gets credited as the author.

I am having trouble determining who the author is. I can get it from the operating system eg. $strAuthor = getlogin(); but this does not return the domain.

Other parts of our application use

use TeamSite::CGI_lite;
my $cgi = TeamSite::CGI_lite->new();
$cgi->parse_data();
my $user_name = $cgi->{'form'}{'user_name'};

and it returns the domain and username and I want to do the same so that all our authors match.

Has anyone done something similar?

We have the following products installed:
- TeamSite 5.0.2
- TeamSite Templating 5.0.2

and are on a Windows environment.

Thanks, Shell.
