Depends how fussy you are about the meaning of words.
In some corners of the OpenID universe, there is no SSO; there is only "CCA" - cross-company authentication.
SSO is a fighting term, between vendors. There is "real" SSO, half-baked SSO, SSO that is not SSO, SSO that is simple rather than single, and SSO such as OpenID - all these being manifestations of folks trying to bundle some or other "control policy" into the obvious benefit that folk clearly want : be able to apply 1 credential on lots of sites and stop sharing those (bad) passwords!
