CA SiteMinder® and CA SSO Integration Prerequisites

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

Install and configure CA SSO.
Note: When installing the CA SSO Policy Server, gather the following:
- An SSO administrator name and password. The CA 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. The CA SiteMinder® Policy Server smetssocookie active response requires this value.
Be sure that the CA 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.
Consider the following:
- If the integration is to operate in FIPS–only mode, CA SiteMinder® Policy Servers must be operating at r12.0 SP1 CR3 or later. If necessary, upgrade the CA SiteMinder® Policy Servers that are to communicate with the CA SSO Policy Server.
- Be sure 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. For more information, see the 12.51 CA SiteMinder® Platform Support Matrix.
