DeVry Inc, Wood Dale, IL                                                                                        May 2009 to Sep 2011

Senior Java Developer, IdM (Identity Management) Team

This project comprises of Identity Management (IdM) of all DeVry Students and Staff. Identity info is being managed in Oracle Internet Directory (OID). The identity info originates from SunGard HE Banner Enterprise Information System (BEIS) and sent to IdM Identity Service Web Service, which then pushes that info to OID and this info is being synchronized with many provisioning targets using Oracle’s DIP (Directory Integration & Provisioning) service. Currently, the info is being provisioned to Microsoft AD (Active Directory), SUN Luminis LDAP, AlFresco CRM web service, Banner Enterprise IN Web Service.

 

Roles & Responsibilities:

 

Directory Integration and Provisioning Plug-In: Design and Development.

To provision OID identity information into AD, Oracle’s Directory Information Provisioning           (DIP) service is used. DIP is configured to invoke configured Java PlugIn based on change in values of given (configured) OID schema attributes. This plug-in is written using Spring framework, where DIP’s profile name is tied to Spring Bean. When a certain profile gets instantiated by DIP, the corresponding Spring Bean would do its job. Currently there are several Spring Beans to provision the info into AD, Alfresco CRM Web Service, SUN Luminis LDAP for portal user authentication, and Banner Enterprise IN Web Service.

The Alfresco/Any future partner WS Sender framework is designed to handle variable data load, it creates variable number of Sender Threads which would be there job and the Master thread would keep of checking on the Sender (worker) Threads. So if Workers finish their job first they notify the Master and return the result, or otherwise if Workers timed out then Master would join the Threads and collect the result. So this way this has been a very efficient model to deal with High Bulk Load and High Speed.

 

Active Directory (AD) bulk provisioning utility: Design and Development.

Before GO LIVE all the existing students and staff should be provisioned as bulk in AD. This tool provisions users and it is multi-threaded.

 

Oracle Internet Directory (OID) utility: Analysis, Design and Development.

Before GO LIVE all the existing students and staff password should be synchronized from existing OID to new OID server. Also, some of other attributes should be set in new OID based on some filters. This is generic utility to update the entries in OID and it is multi-threaded.

 

IdM Toolkit: Development

There are many systems in this IdM Project where the information sits, and this Toolkit is a single place to manage information. The Person Identity information flows from Banner Enterprise into OID, and Audit info goes into DB. From OID the identity goes to AD. And from OID, information is also provisioned to Luminis LDAP, and Alfresco. IdM Toolkit collects the information from all the above systems and puts on UI.

This Toolkit UI application is written using Spring Framework, Spring MVC, Spring LDAP template, Hibernate (all DB native SQL queries externalized in separate hbm file).

 

Identity Service Web Service:  Design and Development.

This Web Service receives the Identity information in SPML v2 (Service Provisioning markup Language) format from Banner Enterprise Proxy and persists into OID (Oracle Internet Directory). Web Service’s skeleton is written (using Axis2’s AXIOM model OMElement)        to receive any SPML v2 XML payload in the SOAP message.

The data from SPML is extracted using XPath queries (specified in properties file), transformed and assigned to Ldap Directory’s Attributes, and then saved into OID using JNDI API. The data transformation is done through the use Jython scripting.

 

ESB: To make this WS to be able to take data from multiple sources with different data payload and with different XML namespace, the Oracle ESB has to be placed in front of this WS, so that different data formats could be translated into one uniform data which is handled by this WS. Apache Camel/Mule also appeared to be a suitable choice as Mediator and Router, as in this we could use Camel in Web Servlet format and let Jetty receive call and pass it onto XSL transformer then onto WS.

• Involved in requirement gathering, design, analysis and STS (System Technical Specification) documentation.
• Designed and developed the spring based Provisioning Sync Tool using spring 2.x, Spring LDAP Template, JDBC Template, ORM, AOP and Application Context.
