I've an application that going forward is going to require cross domain authentication using an AD service account across 2 separate organisations - for example domain A application needs to authenticate with domain B backend.
Does anyone know of a way that I could get cross domain authentication working without a domain trust in place between 2 separate organisations - due to security concerns this isn't desirable?
Could AD LDS work in anyway - I believe an AD Trust would still be required? Any other ideas greatly appreciated?
Thanks in advance, PJ
