Who do you think you are, anyway?

Sometimes simply knowing who you are can help a great deal. I just figured out some tricky Active Directory permission issues by tracing out the current WindowsIdentity, like so:

string strCurrentID = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
System.Diagnostics.Trace.WriteLine("Current Impersonated Identity: " + strCurrentID );

Anyhow, I kept getting Unknown error (0x80005000). Problem was, the current user didn't have the proper permissions to our AD store. From an ASP.NET application, this user is: NT AUTHORITY\NETWORK SERVICE. I changed this to a more trusted account, by changing the anonymous user and password in the “Authentication Methods“ tab in the Directory Security tab of the site properties but I then remembered that I also had to adding the following to my web.config file.

Problem solved.

Rom,

Not sure about Page.User, will this show you the current impersonated user? You really need the Windows Identity process in this case.
