If the logon was successful, the ContentManagerService becomes an authenticated service and a string known as a CAM Passport will be sent back to the SDK application in the BiBusHeader. When an SDK application creates an object to represent a Cognos 8 service, that object will contain a property called BIBusHeader. The BIBusHeader represents the SOAP header that is used to communicate with the Cognos 8 server. Within the BIBusHeader, is a property named CAM which in turn contains a property named CAMPassport. The CAM Passport returned by the logon() method is stored in the
CAMPassport property.
In an SDK application, the CAM Passport does not automatically propagate to other services that might be used within the application. Since the ContentManagerService is the only service than can logon and logoff, there needs to be ability to assign the CAM Passport to other services that the SDK application might require (such as the ReportService). This assignment is done simply by copying the BIBusHeader of the ContentManagerService to the BIBusHeader of the other service, thereby making that service an authenticated service.

Cognos 8 SDK -- Logging on
Unless Anonymous access is allowed, when a Cognos 8 SDK application is connected to the Cognos 8 server the application has no implied rights or access permissions. The Cognos 8 SDK application needs to login just as a general user would login to the Cognos portal.
If anonymous access is allowed, the Cognos 8 SDK application will be granted the same rights and permissions as the Anonymous user from the Cognos namespace. If anonymous access is not allowed and a Cognos 8 SDK application does not login, an exception will occur when the SDK application tries to perform an action such as querying the content store or running a report.
All logons and logoffs are performed through the ContentManagerService using the logon() and logoff() methods. None of the other Cognos 8 services can perform a logon or logoff operation.
