How to use WSO2 IS SCIM service through WSO2 ESB

1. WSO2 IS has the SCIM protocol support which is an Open Standard for Identity Provisioning.
More info in: http://hasini-gunasinghe.blogspot.com/2012/11/wso2-identity-server-as-scim-service.html

2. The service endpoint is
https://localhost:9443/wso2/scim/Users 
when IS is started with default ports.

3. This service can be used through an API through WSO2 ESB
ESB configuration:
<api xmlns="http://ws.apache.org/ns/synapse" name="scim" context="/scim">
   <resource methods="POST GET DELETE PUT">
      <inSequence>
         <send>
            <endpoint>
               <address uri="https://localhost:9443/wso2/scim/Users"/>
            </endpoint>
         </send>
      </inSequence>
      <outSequence>
         <send/>
      </outSequence>
   </resource>
</api>

4. The service can then be used with following curl usage commands:

Add user:
curl -v -k --user admin:admin --data "{"schemas":[],"name":{"familyName":"Anthony","givenName":"Mark"},"userName":"mark","password":"mark123","email":"paul@home.com"}" --header "Content-Type:application/json" http://192.168.71.1:8281/scim

Response is:
* About to connect() to 192.168.71.1 port 8281 (#0)
*   Trying 192.168.71.1... connected
* Connected to 192.168.71.1 (192.168.71.1) port 8281 (#0)
* Server auth using Basic with user 'admin'

{"id":"629d21a3-f0b4-4536-a11f-d5f906c8e327","schemas":"urn:scim:schemas:core:1.0","name":{"familyName":"Anthony","givenName":"Mark"},"userName":"mark","meta":{"lastModified":"2013-01-11T14:52:09","location":"https:\/\/localhost:9443\/wso2\/scim\/Users\/629d21a3-f0b4-4536-a11f-d5f906c8e327","created":"2013-01-11T14:52:09"}}

This id can then be used to retrieve the user:
curl -v -k --user admin:admin http://192.168.71.1:8281/scim/629d21a3-f0b4-4536-a11f-d5f906c8e327

The result again is:

*   Trying 192.168.71.1... connected
* Connected to 192.168.71.1 (192.168.71.1) port 8281 (#0)
