  1. Query the LDAP directory (e.g. the AD) with this filter:

    (&(objectCategory=user)(sAMAccountName=<user-logon-name-here>))

    The DN of the object returned is the thing you are looking for.

    Something like this:

    DirectorySearcher ds = new DirectorySearcher(); string userName = WindowsIdentity.GetCurrent().Name; string userFilter = '(&(objectCategory=user)(sAMAccountName={0}))';  ds.SearchScope = SearchScope.Subtree; ds.PropertiesToLoad.Add('distinguishedName'); ds.PageSize = 1; ds.ServerPageTimeLimit = TimeSpan.FromSeconds(2); ds.Filter = string.Format(userFilter, userName);  SearchResult sr = ds.FindOne(); // now do something with sr.Properties['distinguishedName'][0]
