SYMPTOMS

Accessing the Request.ServerVariables("LOGON_USER") variable from Active Server Pages (ASP) returns an empty string.

CAUSE

The LOGON_USER variable is not populated if you use the Allow Anonymous security to access the ASP page.

In order for the LOGON_USER variable to be populated, the user must be authenticated using either Basic or NT Challenge/Response security.

STATUS

This behavior is by design.


Additional query words: allow anonymous LOGON_USER ASP ServerVariables Request
