Understanding single sign-on (SSO) between IBM WebSphere Portal and IBM Lotus Domino

Summary:  This white paper provides an in-depth explanation of how the single sign-on (SSO) feature works between IBM WebSphere Portal and IBM Lotus Domino. Learn the basics of how cookies are written to―and used in―Internet browsers, how the cookies are used to enable SSO, and exactly what is in the token and why it's needed for SSO between two servers. Included are specific details of where the WebSphere Portal and Lotus Domino servers configure each part of the cookie used for SSO, the LTPAToken. Editor's Note: This white paper is the first in a three-part series on SSO to be published over the next few months. See the second paper, "Configuring single sign-on (SSO) between IBM WebSphere Portal and IBM Lotus Domino."
