From the identity impersonate= "false"

Today, the process of the same Crystal Report interaction and Excel interaction can not come out, the Internet to find a solution: the identity impersonate= "true" to identity impersonate= "false".

So, to find the identity impersonate related data, find the comparison system of the introduction:asp.net identification matrix . Details are as follows: asp.net identification matrix page content

The principal object implements the IPrincipal interface and represents a security context for a specific user (code that runs on behalf of that user). The principal object includes the user's identity (as the contained IIdentity object) and any roles that the user belongs to.

ASP.net provides the following principals and identity object implementations:

•	The WindowsPrincipal and WindowsIdentity objects represent users who have authenticated identities using Windows authentication. For these objects, you can automatically get a list of roles from the Windows group to which the Windows user belongs.
•	The GenericPrincipal and genericidentity objects represent users who have authenticated identities using forms authentication or other custom authentication mechanisms. For these objects, get a list of roles, usually obtained from the database, in a custom way.
•	The formsidentity and passportidentity objects represent users who have authenticated identities using form authentication and Passport authentication, respectively.

The following tables illustrate the identification of the results obtained from each variable that holds the IPrincipal and/or IIdentity objects within the scope of the IIS authentication settings. The following abbreviations are used in the table:

•	HttpContext = HttpContext.Current.User, which returns the IPrincipal object that contains the security information for the current WEB request. This is an authenticated Web client.
•	WindowsIdentity = windowsidentity.getcurrent (), which returns the identity of the security context of the currently executing WIN32 thread.
•	Thread = Thread.CurrentPrincipal, which returns the body of the currently executing. NET thread (on the WIN32 thread).
