Systems: Sterling File Gateway (or Sterling B2B Integrator), Sterling External Authentication Server
Actor: Internal application
SEAS is commonly used by SSP to externally authenticate SSH/SFTP pubkeys, however this functionality is available only for SSP and SEAS integration, and not for direct integration with SFG.
Worldpay requires that such functionality is available for direct SI/SFG and SEAS integration, in order to enable external SSH key authentication for internal systems that access SFG directly (not via SSP).
Internal security requirements state that all SFTP public keys used for internal connections are kept in local LDAP. IBM Sterling products currently support this requirement only with SSP, which cannot be used for internal clients which access SFG directly (Trusted Network -> Trusted Network).
