- Alter Service Context(s) within Introduce
- Modify each service context accordingly
- Highlight Service Context, click Modify Service button
- Under Information Page, User Resource Framework Options section, check Secure
- Under Security Page (tab/button at top of dialogue), choose Custom
- Then under Secure Communication tab, check Transport Layer Security, choose Privacy for Communication Method
- Then under Authorization tab, select No for Client should connect anonymously AND select Enforce Authentication for Authorization Mechanism
- Then under Service Credentials tab, select System for Run As
- Add Service Property to your (Main Service) context within Introduce,
- Select Service Properties tab, input the following values:

Description
gridServicePrincipalSeparator

The separator used to encord the gridServicePrincipal and grid user's identity when Using the com.fiveamsolutions.nci.commons.authentication.CommonsGridLoginModule
- Click Add button
- Select Service Properties tab, input the following values:
- Ensure the appropriate Types are included within your grid service, if not add the types (XSDs) by doing the following:
- Import Data Types -> caDSR; Project: caGrid_Metadata_Models (version 1); Package gov.nih.nci.cagrid.metadata.security
- Save your changes within Introduce (must be successful)
- Modify each service context accordingly
- Alter how remote services (eg, EJBs) are authenticated and authorized for each grid service request. As an example, create a
GridSecurityJNDIServiceLocator
class to authenticate using both the Grid User's Identity (eg,/O=caBIG/OU=caGrid/OU=Training/OU=Dorian/CN=coppagridtest
instead of a typical remote service user. In short, you'll base your implementation off of your existing Locator (eg,JNDIServiceLocator
) and replace existing occurrences with the newGridSecurityJNDIServiceLocator
Below is an example that demonstrates the essence of how to code it up your newTip Example GridSecurityJNDIServiceLocator implementation within COPPA PO Grid Service Example GridSecurityJNDIServiceLocator implementation within COPPA PO Grid Service See http://gforge.nci.nih.gov/svnroot/coppa/trunk/code/po-grid/src/gov/nih/nci/coppa/po/grid/remote/GridSecurityJNDIServiceLocator.java for full code
GridSecurityJNDIServiceLocator
class.Note title About example CoreServicesConfiguration
is theServiceConfiguration
for our (Main Service) context that you previously added a Service Property when updating your services using Introduce.Warning GridSecurityJNDIServiceLocator
may not be a singleton (static) within your application as the containedInitialContext
instance needs to reference the Grid Identity for the incoming request by usingSecurityUtils.getCallerIdentity()
.Note While this is recognized as a performance hit, we've yet to figure a better way. If anyone is able to determine a better way, please let the COPPA team know team-po@5amsolutions.com --thanks
