Configuring Single Sign-On (SSO)

You can use single sign-on to connect to a server that is running on any supported platform. You must first configure your IBM® SPSS® Statistics Server, IBM SPSS Statistics client, and IBM SPSS Collaboration and Deployment Services machines. Internal authentication allows the server software to run without root privileges.

If you are using single sign-on to connect to both IBM SPSS Statistics Server and IBM SPSS Collaboration and Deployment Services, you must connect to IBM SPSS Collaboration and Deployment Services before you connect to IBM SPSS Statistics Server.

To inter-operate with most modern, secure Active Directory installations, you must install the high-strength encryption pack for Java because the required encryption algorithms are not supported by default. You must install the pack for both client and server. An error message such as Illegal key size is displayed on the client when a server connection fails because the pack is not installed. See Installing unlimited strength encryption.

Note: Before you configure your SPSS Statistics Server, SPSS Statistics client, and IBM SPSS Collaboration and Deployment Services machines for single sign-on, you must make sure that the machines have access to the domain controller server.

For information on configuring IBM SPSS Collaboration and Deployment Services for single sign-on, see IBM SPSS Collaboration and Deployment Services single sign-on services overview.
