I would like to set up ADFS in a highly available manner and have some questions.
1. Is it possible to install the ADFS components on two DCs use NLB to load balance across them (the goal is to do this on just two servers)? The servers that will be able to access ADFS will be locked down so I'm not worried about the security implications of having ADFS on the DC itself.
2. If I do this, do I need to set up some form of SQL clustering/mirroring? I see some references to this in the ADFS documentation and blogs but do not fully understand what is required here.
