The Data Integration Service can include a web service security header when it sends a SOAP request to the web service provider. The web service security header contains authentication information so the web service provider can authenticate the Data Integration Service.
The Web Service Consumer transformation supplies the user name token. The Data Integration Service creates a separate security SOAP header in the SOAP request and passes the request to the web service provider.
You can use the following types of web service security in a web services connection:
PasswordText. The Data Integration Service does not change the password in the WS-Security SOAP header.
PasswordDigest. The Data Integration Service combines the password with a nonce and a time stamp. The Data Integration Service applies a SHA hash on the password, encodes it in base64 encoding, and uses the encoded password in the SOAP header.
