ALSB already retrieves user names and passwords from service accounts and encodes them in HTTP Authentication headers or as WS-Security user name tokens when required. You do not need to use this function if you only need user names and passwords to be located in HTTP Authentication headers or as WS-Security user name tokens. Use the fn-bea:lookupBasicCredentials function as part of a larger set of XQuery functions that you use to encode a user name and password in a custom transport header or in an application-specific location within the SOAP envelope. See in Using the AquaLogic Service Bus Console.
