You can use the Axis2 Web Service Server Connector to provide a SOAP web service, which is accessible via HTTP/HTTPS.
The logic of such a service is supposed to be implemented as an IBM Security Directory Integrator AssemblyLine, thus leveraging existing IBM Security Directory Integrator components.
The Connector is named after the underlying Axis2 Java™ library: http://ws.apache.org/axis2/.
Both WSDL 1.1 (http://www.w3.org/TR/wsdl/) and WSDL 2.0 (http://www.w3.org/TR/wsdl20/) documents are supported.
Both SOAP 1.1 and SOAP 1.2 protocols are supported. Only literal SOAP messages can be used, encoded SOAP messages are not supported. This is a limitation of the underlying Axis2 library (version 1.4.0.1).
The Axis2 Web Service Server Connector supports Server Mode only.
