When integrating Identity Manager and SiteMinder, you may encounter a situation where the Identity Manager objects are completely functional, but they do not appear properly in SiteMinder's WAM UI or in XPSExplorer.
You will see the IMSDirectory and IMSEnvironment objects are visible in the menu, but when drilling down, no objects are shown.
This scenario occurs when the IMSInstalled registry flag is not set on the policy server in question.
This refers to the Windows operating system of the policy server machines where Identity Manager's extensions were installed:
If your Windows is 32-bit then:
[HKEY_LOCAL_MACHINE\SOFTWARE\<YOUR_MACHINE>\Netegrity\SiteMinder\CurrentVersion]
"IMSInstalled"="8.0
If your Windows is 64-bit then:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Netegrity\SiteMinder\CurrentVersion]
"IMSInstalled"="8.0
