SiteMinder and CA SSO Integration Prerequisites

Before configuring a single sign-on integration between SiteMinder and CA SSO:

1. Install and configure CA SSO.

   Note: Ensure you install and configure the CA SSO Policy Server in an LDAP database. Installing the CA SSO Policy Server in an eTrust Access Control database causes the CA SSO/SiteMinder integration to fail. More installation information exists in the CA SSO documentation. When installing the CA SSO Policy Server, keep track of the following:

   • An SSO administrator name and password. The SiteMinder Policy Server uses the administrator name and password when authenticating to the CA SSO Policy Server through the smauthetsso authentication scheme.
   • The SSO ticket encryption key, as it is needed by the SiteMinder Policy Server's smetssocookie active response.
2. Ensure that the SiteMinder environment and the CA SSO environment are operating in the same FIPS mode (AES encryption) of operation.

   Important! The integration fails if both environments are not operating in the same FIPS mode of operation.

3. Consider the following:
   • (Windows) If your SiteMinder Policy Servers are operating at r12.0 SP2 CR3 or later, install the VC8 Redistributable package on each SiteMinder Policy Server that will be communicating with the CA SSO Policy Server. The VC8 Redistributable package installs runtime components of Visual C++ Libraries required for the integration.

     Note: The package (vcredist_x86.exe) is located in SiteMinder\bin.

   • If the integration is to operate in FIPS-only mode, SiteMinder Policy Servers must be operating at r12.0 SP2 CR3 or later. If necessary, upgrade the SiteMinder Policy Servers that will be communicating with the CA SSO Policy Server.
4. Refer to the r12.0 SP2 SiteMinder Platform Support Matrix to ensure that operating systems on which the Policy Servers are installed support the smauthetsso authentication scheme. The integration requires that you configure the smauthetsso authentication scheme.
