This article describes the features and fixes that are included in Service Pack 2 (SP2) for Microsoft Forefront Unified Access Gateway (UAG) 2010.
Features that are included and issues that are fixed in Service Pack 2
Forefront UAG 2010 SP2 includes the following features:
Improved Microsoft SharePoint 2010 support
Forefront UAG 2010 SP2 lets users authenticate to a trunk by using Microsoft Office Forms-Based Authentication (MSOFBA) when the trunk uses Active Directory Federation Services (AD FS) 2.0 for authentication.
Improved Active Directory Federation Services 2.0 support
You can provide remote employees and partner employees with access to published applications that have AD FS 2.0 enabled. For example, you can do the following:
Use AD FS multi-namespace support: Multi-namespace support for AD FS 2.0 lets you use a single AD FS 2.0 server that has multiple Forefront UAG trunks when the fully qualified domain names (FQDNs or public host names) of the trunks are in different domains. For example, the FQDN of the first trunk is portal.contoso.com, and the FQDN of the second trunk is portal.fabrikam.com. Both trunks can be configured to perform AD FS authentication by using the same AD FS 2.0 server (sts.contoso.com). In this kind of deployment, the AD FS 2.0 server is published through one of the Forefront UAG trunks or by an AD FS proxy that is parallel to Forefront UAG.
Use the AD FS proxy to publish the AD FS 2.0 server: Publishing the AD FS 2.0 server by using an AD FS proxy has many advantages over publishing the AD FS 2.0 server through Forefront UAG. These advantages include support for Office 365 authentication and mobile devices.
Enable complex topologies: You can use Forefront UAG to publish a SharePoint website that is located in one site when the AD FS server is located in another site.
Added client devices
Forefront UAG 2010 SP2 lets users connect to the following mobile devices:
Windows Phone 7.5
iOS 5.x on iPad and iPhone
Android 4.x on tablets and phones
