ADFS 2.0 update rollup update 2

Microsoft released another update for ADFS 2.0 as rollup update. So we are now at rollup update 2.

Unlike rollup updates for Exchange the rollup updates for ADFS 2.0 are released as hotfixes and you have to request them first and you cannot just download them.

The Update Rollup 2 update is a cumulative update package that contains all the fixes and new features that were contained in Update Rollup 1.

RU2 has a new feature: support for RelayState.

Before you had to develop your own workaround. Jonas Syrstad published an article about this before:

For RU2 Microsoft published an good article about RelayState

If you now ask what RelayState is, well it is an additional parameter in an IdP-initiated scenario what tells the resource provider where to go next after authentication verification.
