Moved to Web Gateway for better support.
From the Product Guide, Single sign-on chapter:
To view connector templates in the user interface, select Policy | Lists. In the Lists tree, expand System
Lists | SSO Catalog. Select Custom connectors, then click the Add icon. In the Add Connector dialog box, open
the Template drop-down list. Notice that the generic connector templates are at the top of the list.
Have you checked when your SSO catalog was last updated? You can check by going to Dashboard > Charts and Tables > System Summary > Update Status Box and scroll down in that box to the SSO Catalog field for the version and last update date.
