Question

I am using windows authentication within an ASP.NET application. I am wondering how to best get the objectGuid from the currently logged in user?

You can do this with the System.DirectoryServices namespace.

Dim entry As DirectoryServices.DirectoryEntry Dim mySearcher As System.DirectoryServices.DirectorySearcher Dim result As System.DirectoryServices.SearchResult Dim myEntry As DirectoryEntry Dim domainName As String Dim userId As String Dim objectGuid As Guid  'Split the username into domain and userid parts domainName = Page.User.Identity.Name.Substring(0, Page.User.Identity.Name.IndexOf('\')) userId = Page.User.Identity.Name.Substring(Page.User.Identity.Name.IndexOf('\') + 1)  'Start at the top level domain entry = New DirectoryEntry(domainName)  mySearcher = New DirectorySearcher(entry)  'Build a filter for just the user mySearcher.Filter = ('(&(anr=' & userId & ')(objectClass=user))')  'Get the search result ... result = mySearcher.FindOne  '... and then get the AD entry that goes with it myEntry = result.GetDirectoryEntry  'The Guid property is the objectGuid objectGuid = myEntry.Guid 

There might be a better way to do this, but this works!
