Extended authentication checks (sender checking) are performed for partner systems that to not use authentication. Inbound requests are checked with the aid of the instance identification in order to ascertain whether the calling system has a valid entry in the partner list. openFT offers via sender checking the possibility of checking not only the processor name, but also the transport address.
The extended sender checking can be enabled globally for openFT partners via operating parameters or just for specific partners.
The global setting applies to all partners for which the "Partner attributes" automatic mechanism is active.
Extended sender verification is of no relevance for dynamic partners because these are always identified via the transport address.
If the authentication check returns a negative result, the request is rejected.
Special features of FTAM partners
On BS2000 systems the sender check for FTAM partners is always performed via the transport address. On Unix and Windows systems an FTAM partner can additionally be identified via the Application Entity Title which is independent of the partner‘s address. Operation parameter settings specify whether the sender check is performed via transport address, via AET or via both. For FTAM partner a partner-specific setting is not possible.
Special features of FTP partners
In the case of FTP partners, the sender check operates exclusively via the transport address. Consequently the "extended sender verification" attribute is ineffective for FTP partners and is also not displayed.
