After I did research on TechNet, I found that ADFS 2.0 is an SSO solution for web-based applications or a federation service for web based applications.

I have a simple question about ADFS 2.0.

Table of Contents


Company A (site A)

Company B (site B)

I can establish the relationship between these 2 companies by “trust relationship”.


Can I use ADFS 2.0 to do this job?


You want to make Site A of Company A and Site B of Company B get authenticated by ACS (actual identity provider could be different for different companies). It is perfectly possible. Both the sites should use the same ACS or the 2 ACS should have the same definition.
