CAPTURING LOGON INFORMATION FROM ACTIVE DIRECTORY USING ASP.NET WEB APPLICATION AUTHENTICATION

Question

Hi,


We have developed a web application in which we authenticate the user against Active Directory. We need to capture the users who have not logged into the application from past 5 days. We tried using "lastlogon" attribute, but it is not getting updated always the user is authenticated against Active Directory, So how can we acheive this?
