[20] Clarity and Windows 2008 Active Directory

Infrastructure group was rolling out Active Directory upgrade to Windows 2008. Clarity 12.0.x or below doesn't support Windows 2008 Active Directory.

We worked with Clarity and Microsoft team to find a solution. We didn't have Clarity version that supports 2008 AD and Infrastructure team didn't want to stop upgrading to Windows 2008 AD.

After a long battle and with so many calls/emails with Microsoft, we got a fix from them. This needs a registry change in Active Directory Server. It was tested and finally deployed on all Active Directory Servers. Now Clarity (12.0.x) runs fine with Windows 2008 AD.

[ Make following Registry changes in Windows 2008 R2 Domain controller servers]

HKLM\System\CurrentControlSet\Services\NTDS\Parameters
Add String value “DSA Heuristics”
Set the value to 000000000001
