Matt Flynn, in a post about AD password sync, asks:
What if a Virtual Directory could pass authentication requests to Active Directory the way that ADAM does? … Would this be useful functionality in a virtual directory? Is it technically feasible?
+1 for virtual directory pass-through authentication.
It’s definitely technically feasible and works very well to drive consolidation of authentication services. From past experience it’s one of the most powerful benefits of virtual directory technology. In fact, this feature was key to the value proposition and purchasing decision for several of the prominent deployments I’ve worked on. It was also one of the key topics we discussed at the DIDW 2005 Virtual directory panel.
