A service account provides a user name and password that proxy services and business services use for outbound authentication or authentication to a local or remote resource, such as an FTP server or a JMS server. For example, if a business service is required to supply a user name and password for transport-level authentication with a Web Service, you create a service account that specifies the user name and password, then you configure the business service to include the service-account credentials in its outbound requests.
The user names and passwords that you enter in service accounts are used for outbound authentication or for providing credentials to local or remote resources. The user names and passwords that you enter in the Security Configuration module of the ALSB Console are used for inbound authentication and for authenticating administrative requests.
