A Good Case for Control Authority...

[Darran]

I was working with a client this past week and ran onto a really good example of the need for a tiered authorization model around role exchange.  This customer had a very well defined and implemented IBM Tivoli Identity Manager (ITIM) environment in which they had devised a very cool tiered provisioning policy model.  Without giving too much away, they wanted to allowed different internal service provider groups to define allowable entitlement values, whilst retaining control themselves over the base provisioning policies (PP’s) for things like account name space and basic network access security.  In short, they wanted to add a delegated authority model on top of their base PP’s that allowed external groups to define the service attributes that permitted access to their applications...

From a role modeling perspective, this is pretty much the “model merge” use case described in [1], with the addition of the need to define the authority over different provisioning policies on the same service schema (as described in this section).  From a vendor perspective I was (fortunately) able to show exactly how we could achieve this using our own product.  I was also able to point to this effort as a possible path for standardizing the expression and representation of these business rules further down the line.

Its easy to find the needs and use cases, we just have to come together as an industry to define the syntax...
