Environment

 IdentityMinder(Identity Manager): 14.4, 14.5

Integrated with Siteminder

Cause

One of the SiteMinder Policy Servers was missing the registry entry for ‘imsinstalled’ in reference to Identity Manager extensions.  Once we added that registry entry and rebooted, the error has not repeated.

Resolution

See KB 56478 How to: Verifiy if the Identity Minder Extensions are installed on the SiteMinder Policy Server and the Product Documentation - Install SiteMinder Extension

Ensure all Policy Servers have the correct Extension configured:

 

Verify that the following registry setting exists in the CA SSO Policy Server system:

• Linux:

   

  Verify that the following entry exists in sm.registry:

   

  ImsInstalled=8.0; REG_SZ
• Windows:

   

  Verify that setting "ImsInstalled=8.0; REG_SZ" exists in the following location:

   

  HKLM\SOFTWARE\Netegrity\SiteMinder\CurrentVersion
