Few weeks ago I wrote about FIM 2010 support for Windows 2008 R2 Active Directory environment with Recycle Bin enabled. Basically it wasn't supported configuration at that time. But world is changing … and FIM as well.
Few days ago FIM 2010 Update 1 was released to Windows Update and also Windows Catalog. You can use Windows Catalog to download this update in case Your FIM can't access Internet or is not configured to update automatically.
This update brings also support for AD with Recycle Bin enabled for FIM Active Directory MA and synchronization engine. Prerequisite for this update is hotfix described in KB 979214 which brings changes to DirSync control behavior. This hotfix might be also useful if You have application which uses DirSync control in conjunction with Windows 2008 R2 directory.
Unfortunately there still is no update for this issue for ILM 2007 FP1, which still will have problems with importing some changes when Recycle Bin will be enabled. Hopefully some solution will be released soon.
