1. Copy XPSSecurity from the CA SSO (Siteminder) Policy Server installation binaries
Screenshot was captured from r12.52 version.
2. The XPSSecurity need to match the policy server version that you are using and therefore need to copy from the installation binaries that you used. This applied to other version (R12.5, 12.51, 12.52)
to the <Policy server Install Dir>/bin directory.
Note: XPSSecurity is found in the installation binaries along with “smreg” and is NOT copied to the \bin directory during installation.
