I have been trying to perform security validation in a page using the credentials of the domain users ...
However, when I try to get the value in
Code:
HttpContext.Current.User.Identity.Name
is always returned blank.

PS: When I run the code in the IDE is returned "domain\user" ... but when the page is hosted on a IIS server, the returned value is always blank.

Any help? Thx in advance.
Greetings
