Easiest is to use a dynamic host page<https://developers.google.com/web-toolkit/articles/dynamic_host_page>. The token passed by the SSO is processed on the server-side and the user info (along with a token for the app and/or a session/cookie) is written in a <script> in the page, which is read from the GWT app using either a Dictionary or a JSNI method. Have a look at the guice-rf-activity archetype in https://github.com/tbroyer/gwt-maven-archetypes. Usage with a SSO shouldn't be much different. BTW, this is more or less what Google does for all their apps (GMail, Groups, etc.)
