I've been using the term "Single Source" for authentication schemes that use a single authentication source (e.g. a single LDAP service) but are not Single Sign-on. i.e. You have to log on more than once, but you are using the same credentials.

Is there a commonly used technical term or acronym for "Single Source" authentication? I couldn't find one.

Perhaps "Centralized Authentication".

It's only a preference, but this rings best to me. – nedm Jun 30 '11 at 20:23

I've heard it referred to as "Unified credentials" or "Unified Login".
