Enabling Authentication for a Library Application

Because COM+ library applications are hosted by other processes, their security requirements may be different from those of server applications. If the library application is hosted by a browser, it might need to receive unauthenticated callbacks.

To address this need, you can disable authentication so that the hosting process does not perform security checks for callers of the library application. When you disable authentication, calls to the library application effectively go unauthenticated and all calls to it succeed. For more detail, see Library Application Security. For an overview of authentication in COM+, see Authentication in COM+.

To enable (or disable) authentication for a library application

1. Right-click the COM+ library application for which you are enabling or disabling authentication, and then click Properties.
   
   
2. In the application properties dialog box, click the Security tab.
   
   
3. Under Authentication, select the Enable Authentication check box to enable authentication; clearing the check box disables authentication.
   
   
4. Click OK.

The selected authentication setting takes effect the next time the application is started.
