I'm not sure where you are seeing the canadminusers error message?

Check the file /core/vb/api/user.php line 1999, 2069 and 2083 and you'll see what I'm talking about.

There is a check for $canadminusers that allows you to bypass several registration checks. However if $canadminusers is false then it will throw an exception "signing_up_but_currently_logged_in_msg" if the user is already logged in but does not have the canadminusers permission. It's the only line of code in the entire file that throws that specific exception.
